General Information
The original cable is shielded to avoid interference from other sources and resulting unwanted acceleration or deceleration.

The voltage from both sensors ramps linearly from the fully released position to the fully depressed position[1]. The pedal should be supplied with a reasonable stable and accurate 5V supply to ensure a proper readout.
