you want to activate something on the first touch, then deactivate it when touching again, like a
switch. You can also solder a wire to the middle pad and create your own capacitive pad if the
built-in one isn't suited to your project.
If you want to save power, the LED can be disconnected from the output pin (cut the trace
between the jumper marked as such). We designed this breakout to have infinite time-out. The
chip does support having the sensor time-out, so for example, if something is turned on, it will
eventually turn off on its own. If you'd like to use this mode, cut the TIMER jumper and then
connect a resistor/capacitor to the TIME pin. Check the datasheet for how to calculate the TIME
pin to match your desired timeout.
Comes with a fully assembled board, and a small stick of 0.1" header so you can solder and
plug it into a breadboard. For additional contacts, we suggest using copper foil, then solder a
wire that connects from the foil pad to the breakout.
The datasheet has many details on sensitivity, power usage, etc.
