In this project I will show you how I "hacked" a kids game called "Looping Louie". This way the speed of the toy airplane receives a big speed boost and makes the game more fun and difficult for adults. You can control the speed with a potentiometer from -9V up to +9V or choose one of the three random modes (easy,medium and hard) which randomly selects a speed value and direction.

Step 1: Watch the Video!

The video gives you all information you need to build this on your own. But here I will also present you my parts list, schematic, pics and the arduino sketch.

Step 2: Order Your Parts!

Here you can find all the parts that I used in this project. Feel free to order them with the given links (affiliate links).

Step 3: Build the Circuit!

Here you can find the schematic that I made for the project. Feel free to build your own board design but you can also use my own design as a reference.

Step 4: Upload the Code!

Here you can find the Arduino Code that I used in this project. I used an FTDI breakout to program my Atmega328P but you can also just place it inside an Arduino Uno and program it this way.
