I had always thought it’d be fun to create something that controls a vehicle’s horn. This little thought of mine quickly motivated me to experiment and see if I could, in fact, create something fun. Without too much thought, I quickly started thinking about how I would accomplish this and what it should do.
The final idea came out to be a simple interface that allowed the user to program their own functions on the fly. The user could bush the one button to cycle functions while the other activated the function. The user could then push both buttons to enter programming mode and customize it to their liking. With the prototype done, all that is left to do is build a proper board and fit it into an enclosure.
