Tutorial: Using EEPROM on the ATTiny Series of microcontrollers

Intro

This is the first tutorial by Barium Electronics that will be dealing with using the internal EEPROM of an ATTiny using the Arduino IDE and also using the AVR EEPROM library.

The Arduino EEPROM library is compatible with the ATTiny range of AVR microcontrollers as the library itself is built on the standard Atmel AVR avr/eeprom.h 'library' so it is compatible with all the AVR microcontrollers.

This was originally written back in 2016 (wow...) so some things may not match what people have floating around now :)

Things needed:

ATTiny of your choice, I prefer the t85
ISP programmer/ArduinoISP (Pocket ISP, USBasp)
Breadboard
Cup of coffee
