Items like the Rotary Encoder can be infuriating to find in ARC Raiders. Sometimes you can’t walk two feet without tripping over the things, or can complete a dozen runs and not see a single one.

When you’re trying to learn how an algorithm works, it’s not always easy to visualize what’s going on. Well, except for maybe binary sort, thanks to the phone book. Professor [thatguyer] is a computer ...

const int encoderPinsA[NUM_ENCODERS] = { 10, 8, 6, 4, 2 }; // Encoder A pins; any PCINT pin const int encoderPinsB[NUM_ENCODERS] = { 11, 9, 7, 5, 3 }; // Encoder B pins; arbitrary - pick any IO #ifdef ...

//A rising pulse from encodenren activated ai0(). AttachInterrupt 0 is DigitalPin nr 2 on moust Arduino. attachInterrupt(0, ai0, RISING); //B rising pulse from encodenren activated ai1().
