Adafruit 1374 standalone momentary capacitive touch sensor breakout
Adafruit standalone capacitive touch sensor breakout momentary or toggle adafruit 1374 the adafruit standalone momentary capacitive touch sensor breakout boards operate without the need for a microcontroller using an at42qt1010 sensor chip when a touch is sensed an on board led lights and the output pin goes high logic 1 it goes low logic 0 again when the touch is removed you can save power by isolating the led by cutting a trace on the board its ok the trace was specifically place
