Lottery Machine

I will introduce an interesting and challenging device created with Arduino. This device consists of four holes and a central rotating disk. Players need to place the ball into one of the holes and receive a random bonus score. Let's delve deeper into this fascinating device!

Main Body:

The core of this device is a central rotating disk controlled by Arduino. The disk has four holes, and players can drop the ball into one of them from the top. Once the ball enters a hole, Arduino will add the corresponding score to the player based on the hole it falls into.

Here's how the device works: Firstly, the player places the ball at a specific starting point, usually at the top of the device. Then, they trigger a button or switch, which will activate the rotating disk. The disk starts spinning, causing the ball to move on top of it.

As the ball approaches the edge of the disk, it will roll into the nearest hole. This process is random, and players cannot fully control which hole the ball enters. Each hole is associated with a specific score, such as 10 points, 20 points, 30 points, and 50 points. When the ball successfully enters a hole, Arduino adds the corresponding score to the player's total score.

This device not only provides an enjoyable gaming experience but also presents a challenge. Since the ball's entry is random, players need to have quick reflexes and accurate judgment to press the button when the ball enters a hole. This combination of technology and gameplay structure can enhance players' reaction speed and hand-eye coordination.
