Wireless Laser-Gate Timing System for Track and Field

The system consists of two finish line modules and one start line module.

In the finish line, you will have an Arduino UNO, nRF24L01+ Transceiver, LED button pad, photoresistors, LEDs, plastic enclosure, and tripod together with my Finish Line PCB. This module acts as the master, from the LED button pad you will decide when to start the timer.

On the opposite side of the track, you will have a laser that is aligned with the photoresistors. You can either buy a Keyes laser module, a 3.3V regulator, a 9V battery, and my Laser Module PCB, or you can provide your own laser pointer. What matters is that the laser is in a steady position and provides enough light.

In the start line, you will have an Arduino UNO, nRF24L01+ Transceiver, speaker, LEDs, plastic enclosure, and my Start Line PCB. This module is in constant communication with the master and uses an LED to inform the user that it is still connected. When measuring time, the LED will change color.
