4 x Capacitive Touch
Capacitive touch sensing allows you to add human-
triggered control to your robot. When you touch the pad
(either directly or through an alligator clip, copper tape
or conductive ink) the Crickit can detect that signal. We
give you four capacitive touch inputs with alligator/croc
clip compatible PCB pads.
Capacitive touch works best with highly-conductive materials like metal
But you can have the metal also connect to salty-wet items such as fruit or water. However, do not try to dunk the
Crickit into water or squish a grape into the pads - use an alligator clip!
Bonus: if you absolutely need more signal I/O pins, all four capacitive touch pads can also act as analog/digital
signal I/O pins!
The seesaw chip on the Crickit does all the management of these pins so your Feather, micro:bit or CPX does not
directly control them, it must send a message to Crickit. They are on seesaw pins 4, 5, 6, 7 in order.
NeoPixel Drive
Blinky lights will make your robot fun and fashionable.
And we've made it really easy to add NeoPixels
(WS2812/WS2811/SK6812 chipsets) to your project. The
Crickit has a 3-terminal block connector with Ground,
Signal and 5V power. The signal line has a level shifter
on it so it will be 5V logic level, for nice clean signals.
This output is slightly different depending on what kind of Crickit you have
add external resistors to Vcc or Ground to read things such as buttons where a resistor is needed.
