Modular system with single-chip Atmel AVR microprocessor for measuring at outdoor competitions

This diploma thesis deals with the design, construction and programming of universal modular system of timekeeping for children´s outdoor sports games. The basis of this system are single-chip AVR microcontrollers Atmel ATmega 32 and ATmega 328. Data transmission between the modules is realized by a wireless serial port HC-12th. The system is applicable to multiple types of competitions with different types of sensors for time measuring, and it is independent of the continuous supply of electricity
