Additionally, I am also in need of an Arduino program to make a lap timer.
The board: Mega 2560
The Sensors: Sharp Proximity sensors = (no contact triggering is a must)
LCD display: TBD
THe Idea: how long it takes ( seconds/minutes) for my Trolley to travel 10feet of track and display it on a lcd screen and be resettable. Something similar to a Slot Car lap timing system.
