Hi, welcome to Electro Pros. in this tutorial
i'm gonna show you how to make fire
alarm using nodemcu. so let's get started
for making this project you will need a
node mcu
a flame sensor
some jumper wires a breadboard
a micro USB cable
first connect the flame sensor's
ground pin to the nodemcu's
ground pin
then connect the VCC pin of the flame
sensor to the VIN
pin of the nodemcu
then connect the output
of the flame sensor to the
digital i/o first pin
then power it up
so let's see the blink part
then write the wi-fi credentials
then write the authentication code for
blynk
then upload
the code it's now compiling
it is uploading
done uploading if you like this video
