Planning another Arduino build? If you’re just doing something simple like switching a relay or powering a LED, you might want to think about the Digispark. It’s a very small ATtiny-based Arduino ...

Following on from getting an Arduino programme to run on an 8pin ATtiny (ATtiny85), I need to invoke the in-built brown-out reset circuit – because my application involves running from an ...

“Possibly the smallest ATtiny85 based ‘duino derivative”. Indeed! When Olimex announced the Olimexino 85s as the smallest Arduino ever, [Tim] took that as a challenge. His very small Arduino based USB ...

As I did not realise that Arduino is a quick route to getting a stand-alone 8pin microcontroller – an Atmel ATtiny85 – to do something useful. You don’t get all of the functions and performance of an ...

Making an Arduino shield can be simpler than you think. This time I designed one to program Attiny and Atmega microcontrollers, that way I don't have to use a breadboard and make the wiring to program ...
