USB ignition works with Euro Truck Simulator 2 and Farming Simulator 25.

Here's youtube videos showing it working: ETS2: https://youtu.be/WCqYezhcWxc FS25: https://youtube.com/shorts/OTYbKU1yNFo?feature=share

Made with this ignition lock and an Arduino Micro in mind. I used 4x M3x10 and M3 threaded inserts to close the box.

When binding for shutting down the engine, remember to have they key in the on position when clicking the new key to bind, this way "button 3" will be bound. In ETS2 i bound both button 1 and 3 to the engine electrical on/off.

Here's my Arduino code that works with both ETS2 and FS25 It requires this library #include
