This one is designed for teaching the students how to solder SMD components and how to program ATtiny MCU in C.
It's main function is to display a random number (between 1 to 6) just like a real dice. Rolling animation is showed before a number is displayed, and if that number is 6, then it enters "Party Mode".
In "Party Mode" Dicy repeatingly plays animations randomly selected from the six preprogrammed animations. This mode is designed for wearing Dicy like a necklace. There is a hole in one corner of the PCB through which a string can be pulled.
