I used an ATtiny25 to control some LEDs, it generates a number randomly and displays it as a die.
It first displays light sequence, then the random number and it finally goes to sleep, consuming less than 0.1uA untill someone presses the button and wakes it up to start again, battery will last about 250 YEARS when asleep.

The code is fully compatible with arduino and written on the Arduino IDE, for further info on how to program the ATtiny using the arduino ide visit This Guide.

The code can be downloaded here.

Hi, it is not charlieplexed, there are 3 pairs of LEDS and one that is on it's own, using only 4 pins, see the video to find the pairs.

As allways I tend to overdo it. Your way is a much simpler and much nicer way to do it :) kudos to you :D

Hi, I currently have no schematic since this project was built on-the-go, along with the code, but I'll make one soon and upload it.
