TinyDice LED Die (Arduino Compatible)

About: Interested in all kind of projects, mainly electronics but other stuff too! I try t publish everything I make. CONTACT: emihackr97@gmail.com BTW, please like my page on facebook. www.facebook.com/EmilianoV...

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.

he code can be downloaded here.

    Hi, is this line:

    ADCSRA &= ~(1 << ADEN);

    same as writing:

    ADCSRA=0

    Hi, I didn't really document it, so i have no way of doing so, but a better, newer version of it is coming, this time with the full step by step guide.
    ill tell u when I'm done with it.

    Interesting solution. I dont know what his schematic is but here is the basic wiring for the leds if that helps anyone.

    Pin 0 powers 2 leds (bottom left,top right)
    Pin 1 powers 2 leds (middle left, middle right)
    Pin 3 powers 1 led (Center middle )
    Pin 4 powers 2 leds (top left, bottom right)

    to me it looks charlie plexed :) google around on that a bit and i think you should be on your way :)

    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.

    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.
