This breakout board is the simplest way to create a project with
mutiple capacitive touch sensors. No microcontroller is required
here - just power with 1.8 to 5.5VDC and connect up to 5 conductive
pads to the 5 left-hand pins. When a capacitive load is detected (e.g.
a person touches one of the conductive contacts) the corresponding
LED on the right lights up and the output pin goes low. You can use
this to update an existing normal-button project where buttons
connect to ground when pressed.
Note that only one contact will be detected at once (this is to
protect against having a hand brush against two or more contacts at
once.
Comes with a fully assembled board, and a stick of 0.1" header so
you can plug it into a breadboard. For contacts, we suggest using
copper foil, then solder a wire that connects from the foil pad to
the breakout. This board uses the chip in
'standalone' mode only, it cannot be used in I2C mode.
