This wireless project provides a solution for synchronizing remote stop watches and transmits race results to a central pan coordinator.   This design links 14 end devices to a central master radio.  Once the remote stop watches link to the master, the system is ready to record swim race times.  The master sends out a broadcast message to all the remote stop watches to begin the race.  Each stop watch is connected to a capacitive touch panel to detect when to stop the timer.  Each stopwatch sends a unicast message to the master when the race is over.
