Step by step tutorial, with no steps to skip.
The main goal of this tutorial is to show how to make wearable display run by Attiny85 and OLED display SDD1306.
Due to running campaign for ATtiny25/45/85 PCB TINY CHEAP VERSATILE Arduino compatible on Indiegogo I did prototype of wearable display base on natural leather, to show what is possible with ATtiny25/45/85 PCB.
