Description from the creator

Arduino relay circuit and Arduino relay code:
In this video we’ll learn how to use a SainSmart 4-Channel 5V relay module with an Arduino. We also discuss the SainSmart relay board’s capability, its use of optocouplers for optoisolation, and how to hook up the Arduino relay circuit. We use the Arduino to switch a light on and off, demonstrating the relay’s ability to control high voltage loads with an Arduino.

Where you can buy the tools and materials:
[✓] Arduino Uno amzn.to/2zqDqXE
[✓] SainSmart 4-Channel Relay Module amzn.to/2xUvJN7
[✓] YwRobot Breadboard Power Supply Module amzn.to/2yDuwsb
[✓] 9V Power Adapter amzn.to/2yDSF1F
[✓] Extension Cord amzn.to/2xVKxuC
[✓] Breadboards amzn.to/2yDvapn
[✓] Jumper wires amzn.to/2zpiT5E
[✓] Light seen in the video amzn.to/2zrgTto
