I want the coding for this project. The Relay should turn on when the desired temperature is greater than actual temperature. Also tell me to the opposite case when desired temperature is less than the actual temperature.
Just simple coding nothing else.
CONNECTIONS :
REPLAY BOARD:-
In - GPIO2
GND -GND
VCC- +5V
@Gaurang_Sharma this site is not a coding factory and including URGENT in your post just antagonises readers.
From the wider internet find the required code for what you require and then modify it to work with Blynk. You will learn a lot by studying the coding provided by other Blynkers in the “Projects” section.
