A maker has built his own driving pedals for a racing simulator in order to have more control over the design and save money.
He used a load cell for the brake pedal to measure force, rather than position, and a hall effect sensor paired with a spring for the clutch and accelerator.
The former was set at 10Hz, but he was able to increase the frequency to 80Hz by lifting a pin on the HX711 load cell sensor board.
He used 3D printing for stiffness around the pedal stem, controlling the resistance with the infill percentage, and mounted it all on an aluminium extrusion for precise positioning.
The Arduino controller allows it to communicate with the PC as a games controller.
