They don’t call slot machines one-armed bandits for nothing. And although it’s getting harder and harder to find slot machines with actual pull-able handles instead of just big buttons, you can easily simulate the handle at home with the right kind of limit switch, as [Andrew Smith] did with this micro slot machine.
This baby slot machine is built around the Adafruit 5×5 NeoPixel grid, which is an add-on for the QT Py. As you’ll see in the brief demo video after the break, the switch actuates on release, which starts the lights a-spinning. [Andrew] says the constraints of the SAMD21-powered QT Py made this a particularly fun challenge.
Whereas most physical slot machines have different reel sequences, this build uses just one. [Andrew] declared hex values to ID each color, and then created the reel manually with different color frequencies. When the lever is released, the columns are animated and slowly to come to rest at a random offset. You can check out the code on GitHub.
