Racecar - Gate Timer

Author: Jeffrey Wen

Date: 5/24/18

This module provides an electronic timing system for the precise timing of a moving object. We use two laser gates that record the time at which a moving object passes through the gate. By recording the precise starting and ending time, the module can display the total travel time between the two gates on an LCD. This module is ideal for kinematic physics experiments where accurate timing is required. Another set of code is provided, which can calculate the acceleration and velocity of the object given the distance between gates and assuming zero initial velocity.

The presentation material and the code can be downloaded at Racecar Gate Timer.
