Hello all, I've decided to do a project that on the surface I thought would be very simple but I'm actually fairly stuck.
The project is for eye-movement tracking but the code seems to have me totally stumped.
The goal was to have a strip of WS8212b LEDs connected to an Arduino and a pot. When the pot is turned it relates directly to the strip so as you turn it an led lights up and the previous led turns off.
If you turn it quickly the led moves quickly down the line, if you turn it back it the little led will come back down the strip matching the speed.
I'm not really sure what terms to look for or how to even start this, I have fairly basic Arduino skills. Could someone help or point me in the right direction? I've tried the FastLed library but none of the examples helped me understand how to do the code myself
