Arduino laser target game

Do you have good aim? It does not matter, because this Arduino project will help you improve it. This mini game is about building a target that detects a laser so you can practice your aim and your pulse control.

This project includes different game modes that help you improve your accuracy.

Explanation and gameplay of the mini game

The objective of this project is simple: we need to make the laser hit the photoresistor, which in this case acts as our target. Every time the laser hits the photoresistor, the counter increases by one. Once you hit it 5 times, which you can change in the code, the round ends.

Another game mode is trying to keep the laser light on the photoresistor for as long as possible. Every 0.5 seconds the red LED turns on, and once it lights up 5 times, the game ends.

As mentioned before, all these values can be changed very easily in the code. By default the value is 5, but you can set any value you want.

This is a very interesting Arduino project because it helps you understand how photoresistors work and how counters are used in code. It is definitely a recommended mini game.
