Relay Wiring Diagram Arduino. The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino. The connections between the relay module and the arduino are really simple.
Controls the second relay it should be connected to an arduino digital pin if you are using this second relay. We have connected transistor base to arduino pin a0 through a 1k resistor. Between the dht22 vcc and data pin insert a 10k pull up resistor.

The working of the project is based on the functioning of the relay and the ability of arduino to control the relay. The connections between the relay module and the arduino are really simple. Between the dht22 vcc and data pin insert a 10k pull up resistor. Arduino 2 channel relay.
