For my starter project, I built an Electronic Dice Kit. The parts of the Dice Kit include the resistors, the diode, the IC socket, the battery, and the piezo. Resistors regulate the flow of the electric current. The diode allows current to only flow in only one direction. The diode is an example of a directional part, which means that its polarity, or orientation, matters . Then I placed the IC socket which helps hold the chip, or the PIC. Finally, there is a battery under the dice. The piezo is the part that contains the two wires. The PIC can manipulate it’s pins pins to be either inputs (no effect on the outside world, called Hi-Z), or outputs with a high or low value. When the PIC reads an analog value it returns a 10 bit value which represents a decimal value from 0 to 1023. The Dice Kit uses only the last three bits, which is a decimal value from 0 to 7. These results are shifted, giving a result from 1 to 6, plus possibly a zero. If zero is read the analog value is rejected and reread. Once a good value is found, it is displayed on the LEDs. I also had some struggles. Because the battery holder was mounted on the bottom side, I had to desolder a lot of the wires and snip them down as close as possible to the PCB so that it was close enough to the PCB and could be soldered. I also had problems when I would tap the dice on the table. The piezo would not budge, and it would keep reading 1 and nothing else. I fixed this by moving it and flipping it.
