Wire the button module
Connect the button module to the pin the worksheet names, then write the few lines of code that prove the board is reading it.
Do not move on until a press shows up on the LED display every time.
Build the basketball possession arrow
One press flips the arrow to the other team.
Show it to someone who has never seen it and see whether they can tell which team has the ball.
🔘 One press should mean one change
A button held down a beat too long can register as several presses, and your arrow flips twice.
Fix it in the code, not with your finger: wait for the press to end before you let the next one count.
