#071 TinyBlink

A simple blink sketch with an ATTINY85-20PU on a breadboard.

The Build

Here’s a quick video of it in action:

Notes

The objective here is to demonstrate an ATTINY85-20PU chip running independantly on a breadboard.

I’m programming it with Arduino ISP, see the ProgrammingWithArduinoISP project for details on uploading the sketch.

About LEAP

LEAP is my personal collection of electronics projects - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting.

Projects are often inspired by things found wild on the net, or ideas from the many great electronics podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know or send a pull-request.

NOTE: For a while I included various scale modelling projects here too, but I've now split them off into a new repository: check out LittleModelArt if you are looking for these projects.
