Overview
OpenSR v0.5 introduces the Arduino Project system, a powerful new way to build and integrate your own custom sim racing hardware.
Located directly in the OpenSR sidebar, this feature provides a dedicated platform for creators to develop fully custom USB devices. Whether you are building a bespoke steering wheel, a custom button box, or a specialized pedal set, the Arduino Project system allows you to combine high-performance RGB lighting with buttons, encoders, axes, and other inputs into a single, cohesive device.
Supported Device Specifications
The Arduino system is designed to work with addressable RGB NeoPixel/WS2812 LEDs. To ensure optimal performance and stability, the system supports the following maximum capacities per project:
- RPM LEDs: Up to 15 RGB RPM LEDs
- Flag/Warning LEDs: Up to 6 RGB Flag/Warning LEDs
- External LEDs: Up to 24 RGB External LEDs
- Passive LEDs: Up to 100 RGB Passive LEDs (for illuminating device components)
- Buttons: Up to 32 buttons
