This video shows you how to turn an AC load, like a bulb, on and off using a TTP223B touch module with a relay. This demonstration and code will show how to use it with Arduino and without Arduino. You will also learn how to connect it if your relay is different. The last section of the video shows you how to control the time the AC bulb or load is on.
