Raspberry Pi Relay Tutorial
Relay board wiring diagram. Today arduino is being used for a wide range of applications. Connect the side leading to the light bulb to the no terminal of the relay and the side leading to the plug to the c terminal. This post shows how to use a relay module with an arduino board. The 8 channel relay module has its own optocoupler also called opto isolator photocoupler or optical isolator. Arduino is a microcontroller based prototyping board that runs on small dc power. The low voltage side has a set of four pins and a set of three pins.
This pinout image is only a 2 pole diagram for room on the page purposes but you can get the picture here with this one since a 3 pole will just have 1 more set of contacts.
