Hello I’m working on a project where I would like to incorporate a capacitive touch sensor to toggle between brightness(low,medium,high,off). I’m not sure how to start. Any recommendations?
Thank You

Have you got some code for the cap touch sensor to start with?
With that the “toggle” would be simple
enum BRIGHTNESSLEVEL
{ brOFF = 0
, brLOW
, brMED
, brHIGH
};
BRIGHTNESSLEVEL br = brOFF;
...
BRIGHTNESSLEVEL levelUp() {
br++;
if (br > brHIGH) br = brOFF;
return br;
}
Hi Tameim,
If I needed to do something like that, I would get some inspiration here:
and why not, here as well:

scroll down to the section WORKING WITH CAPACITIVE TOUCH

for (int i = 0; i < CRICKIT_NUM_TOUCH; i++)

uint16_t val = crickit.touchRead(i); // read the touch input
if (val > CAPTOUCH_THRESH)
