Don't touch the wire Arduino game

Here is the tutorial for the classic Don't touch the wire game. This project is built entirely with Arduino. It is very easy to assemble and the programming is quite simple. Below we explain step by step how to build it.

Game explanation, objective and how it works

The way this famous mini game works is very simple. The goal is to move a metal loop from one end of the wire to the other without touching it. If you touch the wire, the traditional version gives you a small electric shock, but in this version a light turns on and a buzzer makes a sound.

It also includes a small LED display that counts how many times you touch the wire.

Materials used in the project

The materials used in this project are very simple and should be easy to find. To make things easier, here is a list of all the components.

At the bottom of this image you can see two red wires. The longer one is the wire that the player must follow from one point to the other, while the shorter wire with a loop at the end is the one held by hand.

Arduino code for the project

Below you can find the Arduino code developed specifically for this project. The pins used in the code are the same ones shown in the wiring diagram above.

If you want a more detailed explanation of the different parts of the code and how the game works, we recommend watching the video above.
