The Arduino IDE provides access to these through a function in tools called ‘Burn bootloader’ (available in the Tools menu). In proper Arduinos, this sets appropriate non-volatile flags and downloads ...

Making an Arduino shield can be simpler than you think. This time I designed one to program Attiny and Atmega microcontrollers, that way I don't have to use a breadboard and make the wiring to program ...
