We inspired from Japan sumo robots while creating that board. That robots use multiple trimpots for saving important variables for working program. Also Genesis include 3 trimpots for same purpose. That trimpots directly connected to Arduino Nano’s analog pins (A5, A6, A7). And for Mini sumo robot they serve as Idle Speed, Starting Turn Time, and Edge sensor seen Turn time changers. SPD: Idle Speed while not opponent seen, TRN: Starting Turn Time, Angle Trimpot, ETRN: Edge Turning Time, Angle.
