This thesis focuses on problematics of DAW controllers for sound production software. In this thesis is analysed Mackie Control protocol, one of used communication protocols. There is also an overview of MIDI messages, because Mackie Control protocol is based on MIDI protocol. The thesis contains two own DAW controller designs. First one is based on Mackie Control protocol, second one is based on Generic Remote which offers better customization.

This master thesis deals with a data remote transmission by means of SMS and GPRS technology. The overview of current solutions is presented and then a remote temperature measurement and a data transmission employing a communication module GSM/GPRS TM1 through GSM network using GPRS technology is described. As a response to an impulse, the communication module sends SMS. The technical solution is described in details including HW and SW design of the data transfer and processing equipment using a ATmega 162 microprocessor. This equipment communicates with a server (PC), which displays the measured temperature. A prototype which was used for a validation of the design is also described.

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.
