Ultrasonic distance measurement
Klich, Michal ; Krajsa, Ondřej (referee) ; Lattenberg, Ivo (advisor)
The aim of this bachelor thesis is the design and manufacture of a controlling program of equipment for distance measurement using ultrasonic sensors. It focuses on a detailed description of the whole design from the basic properties of the components to the creation of schemes and PCB design. It subsequently describes in detail the development of controlling software of the equipment. The work briefly describes the most important parts of the code. It summarizes all theoretical and practical knowledge gained during the creation of the whole design, it explains the principles of the functions and works of individual parts and it suggests the best possible options of connection of the whole equipment. It also suggests the best possible variants of the entire circuit. The bachelor thesis also describes the microprocesor AVR ATmega8 from the Atmel Corporaton, which controls the entire device, as well as EEPROM memory chip 24LCXXX, SRF05 ultrasonic sensor and communication with the PC via USB using a microchip FT230XS-R.

Libraries for MSP430G2 microcontrollers
Štěpánek, Adam ; Fedra, Zbyněk (referee) ; Štohanzl, Milan (advisor)
This thesis solves a issue with libraries for microcontrollers MSP430 using them for interfacing internal peripheries such as serial buses or ADC convertor. And also external devices with support of this communication protocols, for example EEPROM memories and expander, or with other interfaces including real time circuit and 8x8 LED matrix display.

Two sensor temperature measurement
Novák, Lukáš ; Háze, Jiří (referee) ; Pavlík, Michal (advisor)
This thesis deals with PCB design and programming of microcontroller AVR, that communicates with WiFi module and Dallas brand thermometers. Wifi module sends data to internet database. In case of communication malfunction information is saved into microcontroler´s EEPROM. When communication is restored information is send to database.

HVAC unit for optical head
Janošík, Tomáš ; Šotner, Roman (referee) ; Kincl, Zdeněk (advisor)
This thesis deals with the design of a HVAC unit for temperature regulation inside an optical head. The unit is completed by functions which optimize its reliability such as checking of fan, heating element, monitoring a supply voltage and saving operating information into the memory. The device communicates with PC via serial interface RS-485. There is also described the possibility to switch the unit to a manual mode, in which the temperature interval is setting by a potentiometers. Solution of this thesis is function prototype.

Altitmeter for RC aircraft models
Kotulek, Milan ; Štohanzl, Milan (referee) ; Prokopec, Jan (advisor)
Bachelor thesis describes a device for measuring and recording flight position RC model, which consist of a microcontroller and a pressure sensor. It measures values of atmosferic pressure and these data are convert by microcontroller to specific height. All is during flight saved to memory and later can be transferred to PC.

Processing of the RC plane model telemetry
Žák, Tomáš ; Fedra, Zbyněk (referee) ; Prokopec, Jan (advisor)
Bachelor’s project focuses on problematic about scanning state of RC plane model, during the fly. In detail there is described internal and external structure, including communication. Main objective of work is design functional board for scanning state of RC plane model, during the fly. There is used akcelerometer for scanning actual state of plane. Accelerometer sends measured data in digital form to microcontroller for evaluating. List of used components is in the enclosure.

Environment control with microcontroller
Králíček, Martin ; Šebesta, Jiří (referee) ; Fedra, Zbyněk (advisor)
This bachelor project focuses on equipment for environment management and check with help of microcontroller. This equipment should enable us to check and manage home environment for example for goldfish, hamsters, spiders and other small pets. Further on, this project describes individual parts of equipment which the ECM-01 consists of. ECM-01 is consists of general block, feed block, relay block with power supply and sensors. The ECM-01 consists of several functional blocks which are controlled by the main microcontroller. The functional blocks contain measurement transducers and action units. The choice of blocks depends both on individual environment and the user. The user can choose which values he needs to control and measure.

Radio Telemetry for RC Aircrafts
Žák, Tomáš ; Fuchs,, Michal (referee) ; Povalač, Aleš (advisor)
Master‘s thesis is focused on problematic about state of RC plane model during the flight. Device is able to measure overload, height, position, pressure and velocity of the flight and store this measurement data to memory medium. The main aim of the master‘s thesis was to design a functional board, firmware for device and design simple program for evaluating of measured data. Involvement consists of five basic parts. First part is microcontroller, which processes measurement data and communicate with others parts. Next is accelerometer. Accelerometer is used for scanning overload of the plane. Barometer is used for measurement of height and pressure. For measuring position and velocity is used GPS module. Last part is memory medium. MicroSD is used as memory medium for storing measurement data. Evaluation of measured data is realized as simple program with base graphical user interface. Program was created in Matlab.
