Hello Guys,
I'm new to electronic boards with a background of programming without experience in hardware, but I'm very interested in hardware too.
Currently, I programmed a NodeMCU ESP8266 to control a relay module (It's working great) to control my old swamp cooler.
This is the old switch currently I'm using to turn on/off the pump and the two speeds motor.
And this is the 4 relay module, I'm using IN1 for the pump, IN2 for motor speed 1, and IN3 for motor speed 2, also for power I'm using from NodeMCU:
The problem is I don't know how to connect wires from the relay module to the cooler wires there're four wires come from cooler as you can see in the first image into the old switch.
Thanks for your help.
