The ARDice - electronic dice based on Arduino

This is a electronic game dice based on Arduino. I saw various schematics with discrete components or IOs more than twenty years ago, but this one with Arduino is easy and fun to make.

Features:

• Random number generation (1-6), the result is displayed on LEDs in a regular 6-sided dice style.
• Makes nice sound and animation when button is pressed.
• Silent mode - press the button during startup to mute all sounds.
• Sleep mode - activates after a period of inactivity.
