[Tobie’s] part of the hack is to use an Arduino and a few buttons as the controller. It’s easy to set up and we think the breadboarded controller approximates the size and weight of an LCD ...

This is an Arduino project called 'Simon Says'. It is essentially a memory game with LEDs and push buttons. The Arduino will play us a sequence of LEDs and the user will try to recreate this pattern ...

Control is via an Arduino Nano, with a few push buttons and a 16 x 2 LCD display for user feedback. Often, completing a first build will reveal all manner of limitations and drawbacks of a design.

This typically includes resistors, push buttons, and sensors ... are components that receive data from the Arduino. This includes LEDs, LCD modules, servo motors, and buzzers.
