8. Trey, Randal, and Hannah are creating a prototype for an amusement ride. On the ride, carts move riders along a track using a chain drive mechanism, and an animatronic display pops up when a cart is detected by the optical sensor. The group successfully creates the program below for the prototype. The ride is working, but Trey wants the carts to go faster up the hill, and the group agrees to this modification.
