For example, connect Digispark ATtiny85 pin 0 to Arduino Uno pin 11, Digispark ATtiny85 pin 1 to Arduino Uno pin 12, etc. Also connect a 10uF capacitor between arduino RST and arduino GND. Note that ...
This repository contains a project for an Arduino hat PCB for downloading a bootloader onto an ATtiny85 microcontroller and a PCB-based USB device for directly sending code to the ATtiny85. All PCB ...
