One of the more interesting applications of this circuit would be to replace or to realize a smart sensor with Arduino. The 4…20 mA standard was introduced a few decades ago, to replace the existing 3 ...

A high speed stepper library for Atmega 168/328p (nano), Atmega32u4, Atmega 2560, ESP32, ESP32S2, ESP32S3, ESP32C3, ESP32C6 and Atmel SAM Due ...

So he decided to replace the stepper motor controller in his turntable and document the process for anyone else who’s scanner might be struggling. Plenty of room for expansion. In the video ...

This latest haul is a gaggle of stepper motor drivers that, with a bit of work, can be reverse engineered and turned into an Arduino. After prying into one of the plastic-enclosed boards ...
