Wesley Kagan’s PorscheKart venture returns with a brand new Arduino-powered F1 steering wheel
November twenty seventh, 2022—
As a part of his ongoing PorscheKart venture, YouTuber Wesley Kagan needed a greater method to steer his V12 custom-built race automobile, because the earlier wheel was merely a mechanical linkage to the entrance steering. As a substitute, this new version would carefully mimic the format and performance of an precise System 1 wheel, full with the entire buttons, dials, switches, and the central display screen.
The bottom of the wheel was fashioned from a laser-cut sheet of aluminum whereas the encircling grips have been painstakingly 3D-printed out of TPU filament. For the electronics, Kagan determined to make use of a pair of Arduino Micros, which have been cut up between dealing with button inputs and driving the show, whereas an Arduino Mega 2560 gathers sensor information and sends it as a string to the 2 boards. Due to the restricted variety of pins, he wired every of the three rotary switches’ output pins to a in a different way valued resistor, thereby letting the analog enter on the Micro know which place is chosen by the incoming voltage.
The ultimate steps of constructing this upgraded steering included connecting the three.5” LCD display screen to one of many Arduino Micro boards and wiring all the things along with the assistance of a pair harnesses to attenuate the mess. Nevertheless, creating the graphics program proved to be a problem as a result of restricted area in ROM for storing the entire draw operate calls, which is why Kagan plans on finally swapping it out for a static picture that has the values filled-in.
