Circuit overview

-
Arduino UNO
- In this code, the arduino was only able to run one task at a time. When attempting to press two buttons, the first task needs to finish before any buttons can be read again.
- There are probably workarounds in Arduino to be able to multitask.

-
ESP32
- Using ESP32, while a task is running, we can also run other tasks. This shows the ability to multitask with ESP32.
