This is a useful addition to my previous article “Arduino EEPROM”. The article is still available. I have provided a link here for convenience https://www.edn.com ...

Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming it with Arduino, I though I would try a more elaborate project, one that has been on the back ...

[Vincenzo] wanted to read some 82S129 bipolar proms, and why not, they were very common in the 1980’s arcade scene. The problem is that its kind of an odd ball part now, and typically only (even) more ...
