You can see the buck converter that takes the 12V input and converts it to 5V output underneath the NodeMCU. To the right you can see the logic level shifter that converts the 3.3V logic output from the NodeMCU to 5V so I don’t have to worry about any voltage drop in the setup. The entire thing is powered from a 10A 12V power supply. The relay behaves like a switch. We make a complete circuit to run the water pump (using a 12V DC power jack) and then use the relay as a way to make or break the circuit. The relay has three terminals on the low current side- VCC, GND, and IN. The IN pin is how the NodeMCU controls the relay.
