Arduino library for reading rotary encoders that output a 2-bit gray code. Rotary r = Rotary(2, 3); void setup() { r.begin(); } void loop() { result = r.process(); if ...

Check the wiring of the rotary encoder. By default, the Arduino inputs are configured without pull-ups. If the module has pull-up resistors in pins A and B, you do not have to do anything. But if ...
