The Capacitive Touch Breakout offers a single capacitive touch button with easy-to-use digital I/O pins.The is a dedicated, single-button capacitive sense chip. The chip handles monitoring a conductive area for touch. As long as a touch (e.g. from a finger) is detected, the keeps the output line high. Otherwise, the line is kept low. You just need to provide a power source (1.8V – 5V) and ground for the work. Additionally, a PAD pin is available if you would like to create your own external electrode.
