Control Home Lights with Touch using TTP223 Touch Sensor and Arduino UNO

In some applications, user input is required to control the functions of a device. There are different kinds of user input methods used in the embedded and digital electronics. The touch sensor is one of them. Touch sensor is an important and widely used input device to interface with a microcontroller and it has made inputting data simpler. There are individual places where the touch sensor can be used, whether it can be a mobile phone or an LCD monitor switch.
