Correct solutions are taken from a lookup table (both on the arduino and in the manual).
Higher difficulties require multiple iterations and increase the blink frequency and pattern length (and therefore lookup table size).
=== Planned ===
* PCB: Lots of resistors dumped onto a board. Find the correct pins to bridge using resistor color codes.
* Balance: Two dots chase each other. One has randomly varying speed, the other's speed is controlled using a potentiometer. If one catches the other, it goes boom.
* High stakes: Spray cold water onto the handler on explosion or failures. Alternative: One button which has to stay pressed the whole time (also makes handling harder) gets wired to a shocker.
