Hello everyone, welcome back to my channel. This is my 4th tutorial on how to drive a RELAY (not a relay module) with an Arduino.
There are hundreds of tutorial available on how to use a “relay module” but I could not find a good one that shows how to use a Relay and not a Relay module. So, here we are to discuss how a relay works and how we can hook it up to an Arduino.
Note: If you do any work with “mains power” such as 120v or 240v AC power wiring, you should always use proper equipments and safety gears and determine whether you have adequate skill and experience or consult a Licensed Electrician. This projects is not intended for use by children.”
