Wireless stopwatch

This bachelor thesis describes the design and implementation of the system of the wireless digital stopwatch for timing. Stopwatch is implemented by microprocessor ATmega16 and the wireless transfer of data by module RFM22. The theoretical part of the work is focused on the description of the all used technologies. The practical part is focused on the design and overall realization of the system. For the processing of the measured results is programmed user application. The final result is the functional prototype of the device including software for microprocessors and computer
