It’s fair to say that building electronic gadgets is easier now than it ever has been in the past. With low-cost modular components, there’s often just a couple dozen lines of code and a few jumper ...

This is a library for the Arduino IDE that helps interface with an MP6602 stepper motor driver. It uses the Arduino SPI library to communicate with the SPI interface (nSCS, SCLK, SDATI, and SDATO) of ...
