Hello. In this video I will be
demonstrating how to use the EasyDriver
stepper motor control board along with
small stepper motors such as this one in
your personal projects. Often I'll be
referring to my new etch-a-sketch machine which
uses two easy drivers and an Arduino
Nano. Stick around till the end of the
video. I plan on doing another time-lapse
and I'll also leave the link for my
etch-a-sketch video of how it works.
Stepper motors are absolutely fantastic

small stepper motors. The EasyDriver
board is readily available both on
Amazon and eBay. I'll leave a link in the
description. I've seen both types, one
with headers pre-installed and one without.
These are great for prototyping projects,
but once you have your project locked
down, I prefer these ones where you
solder directly. Stepper motors use
two electromagnetic coils to control the
position of the shaft. You can think of
this kind of like a compass being
controlled by a magnet. Depending on how
the coils are energized and with what
polarity and strength, the needle points
in different directions. If you go too
www.schmalzhaus.com/EasyDriver/ you'll
find a plethora of information about
this board. Let's start in the top right
corner of this pin-out where you see the
power input of six to thirty volts. You
want to set the voltage depending on
your project needs and we'll talk about
setting that a little bit later. If we go

He visto ambos tipos, uno con encabezados
preinstalados y otro sin él. Estos son 
excelentes para proyectos de creación de 
prototipos, pero una vez que tenga su 
proyecto bloqueado, prefiero estos en los que
suelde directamente. Los motores paso a paso 
utilizan dos bobinas electromagnéticas para
controlar la posición del eje. Puedes pensar 
en esto como una brújula controlada por un imán.
Dependiendo de cómo se energizan
las bobinas y con qué polaridad y resistencia,
la aguja apunta en diferentes direcciones.

over here to the left corner you'll see

have to either go to your drawing for
your motor or ohm out the wires to
determine which wires go to which pins.
On my etch-a-sketch machine, red and green
are coil A and yellow and blue for coil B.
Now it's really not a big deal if you
get coils A and coil B mixed up. That
won't have a big impact on your
performance. What would matter though is
if you had one wire
from one coil and one wire from another.
One thing very important to remember is
not to unplug the wires from the stepper
motor controller while the easy driver is
powered. Doing so will burn up your board
and you will have to buy another one. All
right, moving down to the bottom left
corner you'll see the ground and five
volt output. This can be used to power

Ahora tendrá que ir a su dibujo para su motor
u omitir los cables para determinar
qué cables van a qué pines.
En mi máquina etch-a-sketch, el rojo y el verde
son la bobina A y el amarillo y el azul para la
bobina B. No importa si se mezclan las bobinas
A y B. Eso no tendrá un gran impacto
en su rendimiento.Sin embargo,
lo que importa es si tuviera 
un cable de una
bobina y un cable de otra.
Una cosa muy importante para recordar es no 
desconectar los cables del controlador del motor
paso a paso mientras el EasyDriver está 
encendido. Hacerlo quemará tu tabla y tendrás
que comprar otra. Muy bien, moviéndote hacia
la esquina inferior izquierda verás el suelo

son los que realmente controlan
los motores paso a paso. Para la
dirección, digamos que si estamos altos, tal vez
iría en sentido horario y bajo iría en
sentido antihorario. Se puede cambiar
dependiendo de si conectó la bobina del motor
A y B hacia atrás, pero eso es fácil de
entender. El paso en el pin solo toma un pulso,
por lo que un ALTO seguido de un BAJO
avanzaría el motor paso a paso en un paso.

the bottom right we have the inputs and

Ground this goes to ground on your
Arduino or other microcontroller and
your step and direction are what
actually control the stepper motors. For
direction, say if we're high maybe it
would go clockwise and low would go

to figure out. The step in pin

the sleep input pin or the PFD input. If
you're interested in those read more
about them in the website. Many people
complain about how slow stepper motors
are and while they're not known for
their speed they can be made to spin
faster than most people think. Part of it
could be due to their software, how fast
they're sending the pulses to the
stepper motor. Part can be due to their
voltage setting on their board and we'll
talk about that a little later, but a lot
of it has
do with this MS 1 + MS 2 pins. One of the
things I not a big fan of on the easy
driver board is that by default they are
both set to high (by default) which means that the

Spanish: 
Mi máquina etch-a-sketch tiene doscientos pasos,
así que eso significaría que
tendría que hacer un ALTO y un BAJO doscientas
veces para avanzar una rotación completa.
Nunca he usado el pin de entrada de reposo
o la entrada PFD. Si está interesado en ellos,
lea más sobre ellos en el sitio web.
Muchas personas se quejan de lo lentos que son
que son los motores paso a paso y,
aunque no son conocidos por su velocidad, 
pueden hacer que giren más rápido de lo que 
la mayoría de la gente piensa. Parte de esto
podría deberse a su software, la rapidez
con la que envían los pulsos al motor
paso a paso. Parte puede deberse a su
 configuración de voltaje en su placa y hablaremos
de eso un poco más tarde, pero mucho de esto
tiene que ver con estos pines
MS 1 + MS 2. Una de las cosas de
las que no soy un gran admirador en la placa 
easydriver es que, por defecto, ambas están 
configuradas en alto (por defecto), lo que

Spanish: 
significa que la placa del controlador está 
en la configuración de resolución más alta, lo
que también significa la configuración de velocidad 
más lenta. Entonces, un motor paso a paso que
equivale a 200 pulsos por revolución se convertiría 
en 1600 pulsos por revolución. En caso mio,
donde estaba más preocupado por la velocidad en
en lugar de la resolución, quería que ambos MS 1
+ MS 2 estuvieran en bajo, por lo que para 
hacer eso debes conectar esos pines a uno de los
pines de tierra en el tablero. Otra queja que
escuchará de los usuarios de EasyDriver es el
calor y, en particular, este chip
aquí puede calentarse mucho y quemarlo.
Estos motores también pueden calentarse mucho.
Esto tiene que ver con la configuración actual.
El easydriver es capaz de suministrar 3/4
de un amplificador a cada bobina en el motor 
paso a paso. Eso podría funcionar para uno de
estos grandes motores NEMA 23, pero para
este NEMA 17 que estoy usando en mi 
etch-a-sketch es demasiado. 
Y así, esa corriente adicional significará

driver board are in the highest
resolution setting which also means the
slowest speed setting. So a stepper motor
that is say 200 pulses per revolution would
become 1600 pulses per revolution. In
the case of my etch-a-sketch machine
where I was more concerned with speed
rather than resolution, I wanted both MS
1 + MS 2 set to low, so in order to do
that you need to jumper those pins to
one of the ground pins on the board.
Another complaint you'll hear from easy
driver users is heat and in particular
this chip right here can get very hot
and burn you. These motors as well
can get very hot. This has to do with the
current setting. The easydriver is
capable of sourcing 3/4 of an amp to
each coil in the stepper motor. That
might work for one of these big NEMA 23
motors, but for this NEMA 17 that I'm
using in my etch-a-sketch it's too much.
And so that extra current will mean the

And so that extra current will mean the

motor will get hot the wires will get
hot and eventually it will ruin my motor.
For stepper motorss the higher the current
the higher the holding torque; but each
motor has a limit. In the case of this
motor, the limit is 1/3 of an amp so we
need to adjust the easydriver to be at or
below 1/3 of an amp and I'll show you
how that's done. On each easydriver you'll
find this little screw right here and
this is probably the most overlooked
feature on the EZ driver itself. By
adjusting that screw you can increase or
decrease the current going to each coil
of the stepper motor. If you turn it all
the way to the maximum it will source
the full 3/4 of an amp and if you do
that I would encourage you to put a
heatsink on this chip. But in the case
where I'm trying to get 1/3 of an amp on
my stepper motor I needed to dial it
down. The way to find out how much
current the EZ driver is sourcing is to
connect the black on your multimeter to

Spanish: 
que el motor se calentará, los cables se 
calentarán y eventualmente arruinarán mi motor.
Para motores paso a paso, cuanto mayor es la
corriente, mayor es el par de retención; Pero
cada motor tiene un límite. En el caso de este
motor, el límite es de 1/3 de un amplificador,
por lo que debemos ajustar el EasyDriver para
que sea igual o inferior a 1/3 de un amplificador 
y le mostraré cómo se hace. En cada easydriver
encontrarás este pequeño tornillo aquí y esta
es probablemente la característica más 
olvidada en el controlador EZ. Al ajustar ese
tornillo, puede aumentar o disminuir la 
corriente que va a cada bobina del motor paso a
paso. Si lo cambias todo
el camino al máximo generará el total de 
/4 de un amplificador y si lo haces,
te animo a poner un disipador de calor en este
chip.  Pero en el caso en que estoy tratando
de obtener 1/3 de un amplificador en mi motor
paso a paso, necesitaba reducirlo.
La forma de averiguar cuánta corriente está
generando el controlador EZ es conectar el negro
en su multímetro a uno de estos terminales de

one of these ground terminal
and measure the voltage over here at
test point one. I'm reading about 1.8
volts. When we go to the EZ driver
schematic we can see that a voltage of
2.0 equals a current of one third of an
amp, and that's what I needed to stay
below. So having it set at 1.8 volts
should get me around 300 milliamps or so.
This sheets also important for
determining what size power supply
you'll need. So if you're using the full
5 volts which gives you 833 milliamps
you probably want a 2 amp power supply
because this is just supplying one of
the two coils. If you're using a battery
as your power supply, you may want to
consider turning down the current on
your easydriver controller to the lowest
setting that will give you enough torque
to do your job. One thing to remember
about super motors is that they are
always drawing current (even when they're
not spinning). If you're using a battery

Spanish: 
tierra y medir el voltaje aquí 
en el punto de prueba uno.
Estoy leyendo alrededor de 1.8 voltios.
Cuando vamos al esquema del controlador EZ 
podemos ver que un voltaje de 2.0
es igual a una corriente de un tercio de un
amplificador, y eso es lo que necesitaba para 
permanecer debajo. Por lo tanto, tenerlo
configurado a 1.8 voltios me debería dar
alrededor de 300 miliamperios. Estas hojas
también son importantes para determinar qué 
tamaño de fuente de alimentación necesitará. 
Entonces, si está utilizando los 5 voltios completos,
ylo que le da 833 miliamperios, probablemente
desee una fuente de 2 amperios porque esto solo
porque esto solo está suministrando una de las bobinas. 
Si está utilizando una batería como fuente, es posible
que desee considerar reducir la corriente a la
configuración más baja que le dará suficiente
torque para hacer su trabajo. Una cosa para
recordar acerca de estos motores es que siempre
están tomando corriente (incluso cuando
no están girando). Si está usando una batería,
también puede considerar

diferentes momentos de su programa,
según sus necesidades. Cuando uso una
fuente de alimentación en mi proyecto,
decidí no usar el pin de activación. 
Como puede ver cuando el controlador EZ está 
energizado, no puedo encender el motor a mano.
Cuando coloco un cable de puente
entre el pin de habilitación y el pin de 5  
voltios, puedo girar el motor y dibujar una
línea en el etch-a-sketch aunque el controlador
EZ esté encendido. Esto también se puede hacer
conectando uno de mis pines digitales en
el Arduino al pin de habilitación 
en el controlador easydriver. Dar una
señal ALTA deshabilitaría los motores y una 
eñal BAJA los volvería a encender.
Repasemos un código Arduino realmente
básico para que sus EasyDrivers funcionen con
us motores paso a paso. Lo primero que tenemos
que hacer es asignar los pines Arduino para 
se correspondan con la dirección y las
conexiones escalonadas en su controlador.

English: 
you may also want to consider using the
enable pin to turn on and off the motors
at different times in your program
depending on your needs. Where I'm using
a power supply in my etch-a-sketch
project, I decided not to use the enable
pin. As you can see when the EZ driver is
energized, I'm unable to turn the motor
by hand. When I put a jumper wire in
between the enable pin and the 5 volt
pin, I'm able to turn the motor and draw
a line on the etch-a-sketch even though
the EZ driver is powered up. This could
also be done by connecting one of my
digital pins on the Arduino to the
enable pin on the easydriver. Giving a
HIGH signal would disable the motors
giving a LOW signal would turn them back
on. Let's go over some really basic
Arduino code to get your easydrivers
working with your stepper motors. First
thing we need to do is assign Arduino
pins to correspond with the direction
and step connections on your easydriver.

English: 
In this case, I've used pins 2 and 3. We
want to set those pin modes to output
and we start out by setting them both
LOW. Okay, let's check out the loop now.
Here we have digital write to the step
pin HIGH and the easy driver will
recognize the rising edge and advance
the stepper driver one step. We're going
to hold that there for 5 milliseconds
and then set it back to LOW and then
wait another 5 milliseconds. That
will take approximately 10 milliseconds,
which means that if we have a 200 step
stepper motor it will take about 2
seconds to make a full revolution. Now if
we want to speed that up for example we
could change the delay to be 1
millisecond and that would give us about
2 and a half revs/second on our stepper
motor driver. Ok, so let's say that we
want the motor to go 10 times as fast...
Well couldn't we just change this one 1

Spanish: 
En este caso, he usado los pines 2 y 3. Quremos
configurar esos modos de pin para que salgan
y comenzamos estableciéndolos a ambos
BAJO. Bien, veamos el ciclo ahora.
Aquí tenemos DigitalWrite al paso
pin HIGH y el controlador fácil lo hará
reconocer el borde ascendente y avanzar
El conductor paso a paso un paso. Iban
mantener eso allí por 5 milisegundos
y luego configurarlo de nuevo a BAJO y luego
Espere otros 5 milisegundos. Ese
tomará aproximadamente 10 milisegundos,
lo que significa que si tenemos 200 pasos
motor paso a paso tomará alrededor de 2
segundos para hacer una revolución completa. Ahora si
queremos acelerar eso, por ejemplo, nosotros
podemos cambiar el retraso para ser 1
milisegundos y eso nos daría sobre
2 revoluciones y media por segundo en nuestro paso a paso
conductor del motor. Ok, entonces digamos que nosotros
quieremos que el motor funcione 10 veces más rápido ...
Bueno, ¿no podríamos cambiar esto? 1

microsecond delay? Would that have the
effect that we want? Well, it's not that
simple... Let's get into stepper motors and
explain how we can make our stepper
motors faster and how we know what the
limitations of our stepper motors are.
Before we get into the speed
calculations, let's go back to the
schematic for the motor and check out
some of the most important values for
the speed calculation. First is the step
angle. You see this step angle of 1.8.
That is what corresponds to 200 pulses
per revolution. We also want to look at
the maximum current for this motor which
is 1/3 of an amp. This kind of
counterintuitive, but the higher the
current, the slower the motor will go. So
if you want your motor to go faster, you
actually have to set the current on the
easydriver lower. Inductance is probably
the biggest factor in this whole

Spanish: 
milisegundos de retraso en cien
retraso de microsegundos? ¿Tendría eso el
efecto que queremos? Bueno, no es eso
simple ... Vamos a entrar en motores paso a paso y
explicar cómo podemos hacer nuestro paso a paso
motores más rápidos y cómo sabemos lo que son
las limitaciones de nuestros motores paso a paso son.
Antes de entrar en la velocidad
cálculos, volvamos a la
esquema para el motor y echamos un vistazo
algunos de los valores más importantes para
el cálculo de la velocidad. Primero es el paso
ángulo. Ves este ángulo de paso de 1.8.
Eso es lo que corresponde a 200 pulsos
por revolución. También queremos mirar
la corriente máxima para este motor que
es 1/3 de un amplificador. Este tipo es
contraintuitivo, pero cuanto mayor es el
corriente, más lento irá el motor. Asi que
si quieres que tu motor vaya más rápido,
en realidad tiene que establecer la corriente en el
easydriver más bajo. La inductancia es probablemente
el factor más importante en todo este

current, the slower the motor will go. So
if you want your motor to go faster, you
actually have to set the current on the
easydriver lower. Inductance is probably
the biggest factor in this whole

más lento, su motor paso a paso girará. Asi que

tengo la fórmula para calcular el
velocidad hipotética máxima para su paso a paso
motores y enchufé todos los datos
de la hoja de datos que me da un
velocidad aproximada de 2.2 revoluciones por
segundo. ¿Y qué si quiero mi paso a paso
motor vaya más rápido? ¿Qué puedo hacer al respecto?
Bueno, no puedo cambiar la inductancia y no puedo
cambiar el número de pasos, pero puedo
cambiar la corriente y el voltaje. El ED
puede subir hasta 30 voltios ... ¿y qué si
cambio esto a 24 y recalculo? He

para obtener un poco más de velocidad de tu

slower your stepper motor will turn. So
if you want a fast stepper motor find
one with low inductance. So over here
I have the formula for calculating the
maximum hypothetical speed for your stepper
motors and I plugged in all the data
from the data sheet which gives me an
approximate speed of 2.2 revolutions per
second. So what if I want my stepper
motor to go faster? What can I do about it?
Well I can't change inductance and I can't
change the number of steps, but I can
change the current and voltage. The easy-
driver can go up to 30 volts...so what if
I change this to 24 and recalculate? I've
now doubled my speed. Now let's look at
current. Perhaps I don't need a lot of
torque for my project and I cut the
current in half. I've doubled my speed
again. So you can see there are some ways
to get a little more speed out of your
