In this video I'll show you how to create a "Toggle Switch" puzzle, in which players must turn a series of toggle switches to the correct pattern of on/off states. The solution can be changed at runtime by simply setting the switches to the desired state and then pressing a button - this state will then be saved to the EEPROM of the Arduino, and will then be used as the puzzle solution from then on (even if the Arduino is powered off!).
00:00 - 02:45 Introduction and Demonstration
02:45 - 07:08 Wiring
07:08 - 20:46 Arduino Code
20:46 - 21:18 Wrap Up
