NeoPixel Game Rewards Button Mashing

Who has the fastest thumbs at Maker Faire UK? That’s the question [wellsey1972] sought to answer when he created this simple game using little more than two NeoPixel rings, two chunky arcade buttons, and a Trinket.

The idea is simple: each button push lights up one NeoPixel. The first one to fill up their ring is the winner, and is treated to a ring of flashing green lights. The loser, of course, gets flashing red. Both controllers are hard-wired to a box containing a Trinket, a custom PCB with pull-up resistors, and two sets of solderless terminals. [wellsey1972] smartly re-purposed a cat 5 cable for sleeker wiring.

He has a few ideas for the future, like going wireless, printing smaller controllers, and making winning more difficult via potentiometer. We humbly suggest that the loser be taunted by the cry of a sad tuba. Mash past the break for a brief demo.

If you like lights and simplicity but find this build less than challenging, try building a minimal secret maze game.

  1. nice setup! you could also change it into a reaction testing game. Sound a beeper on the trinket an the first to press the button gets a light. When you press the button before the beeper is sound, a light gets subtracted from you ring. And once in a while sound two or three beeps in a sequence ;)
