GateTiming measures the time an object enters and exits a series of gates where each is constructed of one switch or one photoresistor.
Designed as a simple and low-cost means of timing moving objects, appropriate for science education experiments.The app requires a simple 2 resistor and 1 capacitor circuit connecting the headphone jack to the gates.
Calibration for the circuit and gate configuration accommodates local lighting conditions when photoresistors are used.
A circuit diagram and photo of completed circuit with photoresistors are included.
