Ferrari Stearing weel

Update 27.11.2022: Changed tolerances for nuts and self tapping screws, improved naming scheme of the files, tidied up the f3d file, replaced the center m5 bolt head screws for flat head screws, improved stability by having the m5 flat head screws going through the base plate and the case, added a .docx file for an overview over the different types of screws required, reworked split base plate parts.

Hey guys, this is just another F1 Rim.

For the version with the 7 Segment display, an Arduino Micro should be used since the Pro Micro does not have enough pins. In order to upload the software to it, you can simply use the setup wizard from simhub.

The Nextion version just needs a Pro micro. However, the attached "FerrariNextionButtonsEncoders.ino" Sketch must be uploaded via the Arduino IDE to make the button matrix, the rotary encoders and the Nextion display work at the same time from just one microcontroller. Depending on what pins you use for the LEDs, the rows and columns and the encoders, you may need to change the according pins in the sketch.
The Nextion display must be wired up to the following pins on the Arduino:
5V --> VCC
TX --> RX
RX --> TX
GND --> GND
In order to draw enough power from the Pro Micro, you may have to solder the J1 jumper, which bypasses the voltage regulator of the Pro Micro.
That should not be an issue though, since most USB ports provide stable 5V.
