1 Scope

This little project goes back to a phone call a couple of years ago, where my phone partner told me that he was interested in programming bare bone Atmel 328 ICs. I thought, well this is kind of interesting, because the Arduino platform is quite nice, but there are times where I wanted to have such a little logic platform alone without the need to have a standard Arduino PCB.

So I got myself a couple of Arduino ICs from Sparkfun.

It took me a long time until I had the opportunity and spare time to try them, but now I did and here are my insights!

I followed this instruction here: https://www.kriwanek.de/index.php/de/arduino/boards/410-minimal-arduino-f%C3%BCrs-breadboard

I am taking the circuit from Kriwanek's web page:
