In this slightlymoreadvanced edition of Adventures in Science, we dive into the inner workings of Arduino and microcontrollers. In order to understand how to set up interrupts on microcontrollers, we first need to cover the basics of interacting with registers. We take a simple exampleturn an LED on whenever a button is pressedand rewrite the program to manually read and write to registers on the ATmega328p.
