Build an Electronic Die without Dots
Tired of counting the dots on dice? Then use this circuit instead. Its 7-segment display shows in an unambiguous way the value. Easy-to-build, based on an ATtiny2313 microcontroller and programmed in Bascom. Pressing the push-button will roll the die until the push-button is released. A random number from 1 to 6 will then be shown. A simple way to play quietly during the evenings when the children are in bed.
