Adafruit 1375 Standalone Toggle Capacitive Touch Sensor Breakout

Adafruit Standalone Capacitive Touch Sensor Breakout Momentary or Toggle – Adafruit 1375, The Adafruit Standalone Toggle Capacitive Touch Sensor Breakout boards operate without the need for a microcontroller using an AT42QT1012 sensor chip. They are of the touch-on, touch-off type. When a touch is sensed, an on-board LED will alternately turn on or off and the output pin will follow, high (logic 1) when the LED is on and low (logic 0) when the LED is off. You can save power by isolating the LED by cutting a trace on the board. It’s OK, the trace was specifically placed for just this reason and if you change your mind a small blob of solder will re-enable the LED. Out of the box the switch will remain on until you turn it off, by the same trace cutting trick used for the LED, you can add an RC timing circuit to have it automatically switch off after a specific time. You can also use your own touch pad by connecting it to a solder pad on the board. These are neat little boards with some interesting customisation options. Supplied as an assembled board plus a strip of 0.1in. header pins for you to solder on as required.Please note that these are logic level switches and not power switches.
