Simple scoreboard with arduino.
Arduino sketch to control a 2-team scoreboard.
This is a ‘toy’ I built for my son, but sharing it here as an example of simple Arduino project, for those willing to learn.
It will display 2 digits on a multi-digit 7-segment display, each being the score of the team. Button 1 and 2 increase the value of digits 1 and 2. Button 3 resets both scores to 0.
To make this work, you basically need to know two things: (1) how to display numbers in a 4-digit 7-segment display, and (2) how to set up a button so that you can detect a button-push event from your code:
The two digits corresponding to the scores are displayed at position 1 and 4 of a 4-digit 7-segment display. Check this link to understand how to print digits on multi-digit displays.
When the corresponding button is pressed, the score increases. Check this link to understand how to set up a push-button in Arduino and detect when the button has been pressed.
The code you can find in this repository is basically a combination of these 2 ideas, translated to 2 digits and 3 buttons.
