Nerdy Electronic Dice

thingiverse

It is a simple electronic dice driven by a Chinese replica of Arduino Nano and a 9V battery. The roll of the dice is triggered by one push button on top, which rolls a random number with a random length animation and triggers a buzzer to beep when the animation finishes. A power switch and mute/unmute switch can be found on the side. The source code for this device is available in Thing files.
