Arduino library for the KY-040 Encoder. This library allows the user to connect one or more encoders to any of the interrupt pins supported by your board. The user may then add rotaries that will each ...

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 ...

Knobs are ubiquitous in technology user interfaces, but touchscreens are increasingly replacing them for interface controls. The latest project from [upir] combines a rotating knob with a touchscreen ...

Is it something in the water, or have there been a lot of really cool servo projects lately? Mechaduino is a board that sits on a regular stepper motor and turns it into a servo with a closed loop ...
