Using Sensors with 5V Relays on the Arduino

Learn how to use sensors with the Arduino to turn on and off of a 5V relay. This project will show you how to control high voltage devices with low power sensors and inputs. I use a light bulb to demonstrate but the 5V relay can switch on/off any 120-240V device.
