THE DEVIL SUGGESTS
Build an electronic scoreboard
Make a clear, satisfying score display for table tennis, games night or a made-up family league. Buttons and large numbers are more useful than a feature-packed app nobody opens.
Do it
- Decide what needs displaying: scores, sets or a timer.
- Choose a display, buttons and controller.
- Sketch the button layout before wiring it.
- Program the basic score-up, score-down and reset actions.
- Test it during a real game and adjust the controls.
What next?
Keep the useful notes, photograph the result if there is one, then go and find something else to do.
