[Will] likes his board games but can’t seem to keep from loosing the dice. He’s been using a dice-rolling smartphone app for a while now and decided that it was time to make a dedicated microcontroller dice roller.
The brain behind the dice roller is a chipKIT uC32 microcontroller. Seven output pins are connected to 7 appropriately-arragned LEDs in the top of the dice. There is only one more electrical component, a momentary switch, that is used to re-roll. When the button is pushed, a random number between 1 and 6 is generated and then displayed via the LEDs in true dice fashion. [Will] wrote his own code for this project and makes it available for anyone to download. The case is 3D printed and was designed in Tinkercad, the files of which are also available. The chipKIT is attached to the 3D printed base by a pair of zUNO clips. Find a short video of this thing in action after the break….
