Behind the clock is an Arduino driving a MAX7219 LED controller ... LEDs wired to match what the controller wanted. A rotary encoder tells the processor the position of the arm so the Arduino ...

Each module also has a PWMable bicolor LED for keeping track of each encoder’s setting. If you’re interested in making your own you can buy the PCBs from Tindie or download the project files ...

Now that your rotary encoder hardware is up and running it’s time to tell your Arduino what to do with the encoder signals. There are the two basic ways to read a microcontroller’s digital input. With ...

Makers, developers and Arduino enthusiasts searching for silent stepper drivers with high resolution encoders which are also Arduino compatible. May be interested in the new range of uStepper S ...
