Formula/GT3 Carbon Fibre Steering Wheel & Arduino Shift LIght

Here's my design for Carbon Fibre Formula or GT3 style steering wheel with sequential shift light.
I made this for my Mazda MX5 track car but the wheel uses a standard bolt pattern that will work for mostly any vehicle.
While the wheel base was made with CF, the grips and shift light are all 3d printed.
Also attached is the arduino code for the Nano for the sequential shift light.

Additional/optional considerations:

• Wire to connect between the car, the Arduino and the LEDs
• Your choice of connectors, I used a 3-pin Deutsch DT & GX12 connector
• Tools such as soldering iron & solder, wire cutters, etc.
• Heat shrink
• Breadboard: https://aliexpress.com/item/1005001704653648.html

There are two versions of the 'case' for the LED shift light, one that mounts to the steering wheel, and another that is 'standalone', ideal for mounting to somewhere else on the dashboard of your car.
