Digital dice based on attiny13 microcontroller. Generates random value from 1 to 6 when you press a button.
All you need to build device is atTiny13 microcontroller, 7 LEDs, a button and a battery.
Pin configuration: pin4: ground pin8: VCC pin1: RESET (doesn't used) pin5: PB0 input for next value button pin2,3,6,7: PB1-PB4 outputs for connecting LEDS.
For more information please look at layout (file DDice.lay, can be opened in Sprint Layout). In my layout I added power switcher which is optional element.
