Build a bare-bone Arduino machine workshop

Goal

The goal of this workshop is to be able to create a bare-bone Arduino machine, i.e. a machine that only uses the ATmega328P chip of an Arduino (and not a complete Arduino Uno):

Using the skills taught in this workshop, you can now build you own machines using only the ATmega328P chip.
