I upgraded my project from a large Arduino Uno to a compact Type-C Arduino Nano so it could fit inside my handheld controller case.
I set up the circuit simulation in Wokwi and wired up two analog joysticks to my Nano across pins A0, A1, A2, and A3. When I ran into compilation errors caused by a typo with brackets on a serial print line, I cleaned up the code. I also noticed that moving my joysticks gave inverted reading values, so I map-tested the directions to ensure the logic was solid.
I then designed a specific tank-steering driving logic to handle how my two wheels spin relative to each other for forward, backward, left, and right movements, keeping in mind that the motors face opposite directions on the chassis.
Finally, I categorized my 3D design files into the controller top shell, the chassis base, the full robot frame, and the gearbox drivetrain setup, and packed everything into a comprehensive README file for my GitHub repository.
