An Arduino Uno capacitive touch sensor module detects touch through changes in capacitance. It provides a digital signal when touched, used for creating touch-sensitive interfaces and controls in ...

In this circuit, we power the LEDs through a 3v Arduino pin, but if an external power source is used, one must connect the ground of the Arduino to the ground of the power. The TTP224 module has ...

In this project a TTP223 Touch sensor is interfaced with Arduino uno board to control home lights with just a touch.
