so I just type C and then press Enter
okay it's answer OK so the ATD and the
number is the AT command that you get
to make the sim 800 works
it's the command okay it's the incoming
call in my phone
 
okay welcome back to milliohm.com this
is tutorial about how to use SIM800L
with an Arduino. so let's get started
we need an Arduino SIM800L
and four cable jumper
okay so let's just open the Arduino and
the module first
SIM800L comes with two header and an
antenna a small one we can use the
antenna to boost the signal
okay because the SIM800L cames unsoldered so we need to soldier first we
have to solder the module with the
header so I just need an 5 header
because the last one should be for the
antenna so I just cut the last header
okay let's solder header to the
module
okay after this soldier is finished it's
time to connect the module with Arduino
so just connect the ground the TX and
then RX and then the last one is VCC
we don't have to connect the reset pin
so these four wire that this position I'm
in ground TX RX and VCC okay
connect the ground of module to the ground
of arduino and then the TX topin 10 and
RX to pin 11 and VCC to
5 volt of Arduino
you can also install the antenna if you
need but right now I don't need that
just try with out the antenna you can
solder the antenna if you want and now insert the
SIM card to the module
okay after of the SIM card is in the
module we connect the USB cable to the
computer and then we see the LED in the
top right corner if the LED blinks slow
about once every three seconds means
that we already get the signal but if
the blinks is faster it's mean that we
have no signal or it is looking for a signal
but if the blinks is slow like this it's
mean that we already got the signal okay
it's time to code we have to open our
Arduino IDE now I will try code that this
we can send and receive SMS and then we
can call a phone so I will just upload
the code of course you can copy the code
from the link below at the description
and then you just paste the code in your
arduino IDE and then just upload like
this
make sure that you have to edit the number
with your number so you can send and
receive message you can send the message
to your number and call your number too
okay
it's uploading and okay done uploading
now time to open the serial monitor so you
can see what happening with the module
it should be a delay seven seconds to
get the senior okay it started it was
seven second delay and there is Type S
to send an SMS R to receive an SMS and
C to make a call so just type one
alphabet and you can do this thing okay
first I will type s send an SMS we will
try to send an SMS okay I was just blend
the Serial monitor so you can see the
Arduino and the Serial monitor
at the same time okay I I type s and
then I press ENTER and it should be an
SMS to my phone and that is okay that is
my SMS from SIM800L and the sim
is answering with "OK" you can see that
in the serial monitor the "OK" is the
answer from the SIM and that is the
SMS in my phone hello how are you
you can edit the content in the code of
course okay and now I will try to call
my phone so I just type C and then press
Enter okay it's answer okay the entity
is AT command that send to the module
from Arduino
okay it's the call incoming call from my
number to my phone
You can look closely incoming call to my phone
and there is "NO ANSWER" in this Serial
monitor that mean I don't pick up the
phone okay and then I will try to
receive an SMS so I have to send an SMS
from my phone okay I just type hello
okay and I tap send it's already sent
I think but there is no hello in my Serial
monitor
so let's just try again maybe it's just
pending the SMS is pending so I will try
again to send an SMS
so I send "hi" to my SIM800L and
click send
okay there is a SMS
it's "hi" in my serial monitor it's the
red arrow "hi"
then I just try again "Holla" and send
okay and that is the "Holla" we have the
second SMS from my phone okay I think
that's the tutorial we already send
receive SMS and make a call so see you
