How do I connect the KY-040 to an Arduino?
Typically you connect the module's GND to ground, + to 5 V, and the CLK and DT outputs to digital pins. Use interrupt-capable pins where possible for reliable counting. Confirm the pin labels on your specific module.
What does 20 CPR mean for counting?
CPR 20 means 20 pulse cycles per full revolution on each output. To detect rotation direction, decode the two channels as a quadrature signal, where the order of CLK and DT changes shows the direction.
