Arduino electronic dice on a 7-segment display
Open in the lab ▸Make my own copy
Hold the button and the display spins; let go and it throws 1 to 6. Seven pins drive the seven segments of a common-cathode display, each through its own 220 Ω resistor, and a table of bit patterns turns the number into segments. Open it and press Run: the sketch is inside the board (click the board, then Code). Every part, pin and resistor matches what you would build on a real breadboard; the guided build of the same name has the test sheet and hidden faults.
What is on the bench
12 parts, 19 wires, with a sketch (the program runs in the lab). Boards: Arduino Uno R3.
| Resistor | 7 |
|---|---|
| Arduino Uno R3 | 1 |
| USB charger / port | 1 |
| 7-segment display | 1 |
| Push button | 1 |

The project runs live inside the frame: readers can press buttons, turn knobs and read the meters.
