I2C-RS232 converter
Bednařík, Martin ; Zezula, Radek (referee) ; Zeman, Václav (advisor)
The objective of this thesis is to get familiar with function of I2C bus and microcontrollers AVR and study the principle of connecting microcontroller with the other circuits via this bus. Another goal is to design a device which will enable a communication between personal computer and controlled circuits. A part of this project is production of necessary microcontroller software equipment and to develop own communication protocol. Another output of this project is getting an overview of applied technologies, study possibili-ties of their additional usage and potential enlargement of device with another components.

Meassuring system for building constructions
Vladař, Martin ; Franek, Lešek (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with the measurement of physical quantities in building using decentralized system for data collecting. The system consists of Raspberry Pi as a master device of the system. There are three branches connected to this master device. Each branch consists of up to 32 modules for data-concentration from sensors of physical quantities. The Raspberry Pi has implemented web interface for displaying measured values and system administration.

Universal drive unit
Sehnálek, Lubomír ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
This document deal with design of universal driving unit. For the final solution is required driving unit which will be controled with help of sensory unit placed on the chassis of driving unit. In theoretical part of this labour are examined possibilities of a power, electric motor operation by PWM, kind of chassis and odometry which could be taken into account. From this section is finally chosen concrete configuration which is then described in chapter concerned oneself with driving unit design. Construction of equipment is shown in next chapter where final configuration of equipment is described.

Bioloid Comprehensive Kit
Hujík, Miloš ; Veselý, Miloš (referee) ; Žalud, Luděk (advisor)
The goal of this paper is to suggest suitable senzoric subsystem of mobile robot. There are being analyzed robotic kits of different manufacturers. Their advantages and disadvantages in the theoretical way are being explained in this part and also their opportunities of use in the practical way. In the following parts the work is focused on senzoric subsystems of other manufacturers and again are desribed their advantages and disadvantages. On the last part there is shown own concept of senzoric subsystem. HW and SW implementation is described and there are shown testing data of the conception.

Digital secondary clock
Hortvík, Martin ; Mašek, Petr (referee) ; Marada, Tomáš (advisor)
The aim of this thesis is to design and implement control electronics for digital secondary clocks. The first part is focused on familiarization with the issue of the use of secondary clocks. Subsequently, the work deals with the design of electronics for generating minute pulses. The first part of the proposal is to ensure the correct voltage size and polarity of pulse. The exact timing pulses are provided by a pair of control circuits, Atmega8 microcontroller and RTC. The last part describes the procedure of realization of electronics by making schema, design and manufacture PCB, circuit revive and the implementation of the module into case.

Wireless temperature measurement prepared food
Pospíšil, Jiří ; Matyáš, Pavel (referee) ; Zuth, Daniel (advisor)
The goals of this bachelor's thesis are temperature measurment, data elaboration and wireless data transfer. Theoretical part introduces basic properties and functions of microcontroller and wireless communication. In practial part of this bachelor's thesis is solved temperature measurment task by construction of holow needle with digital sensor inside. Data elaboration is done by A/D converter in ATmega8 – L microcontroller. Wireless data tranfer was done by Bluetooth technology. For the purposes of immediate temperature control was included seven segment LED display. Part of realisation was to design printed circuit board and prototype assembly.

Temperature Measurement with Microcontroller Aid
Harčár, František ; Holý, Miroslav (referee) ; Zuth, Daniel (advisor)
The thesis focuses on possibilities how to use inexpensive microcontrollers for temperature measurement. The designed module is appropriate both for laboratory curriculum, as well as for application in automation industry. A brief introduction is followed by a general explanation of the notion „measurement“ and a measurement history overview. Afterwards, there is a focus on history and development of temperature measurement and types of applied sensors. Conseguently, there is the thesis itself , its description, principles, connection schneme and measurement methodology. Finally, the thesis regards its commitment and findings.

Design and implementation of modules for teaching and developing applications with microcontroller Atmel AVR
LANGMAJER, Miroslav
This thesis is based on the design and production of teaching kits with expansion modules which are based on the Atmel AVR microcontroller. Kit consists of a plate containing processes and basic power modules directly on the board and expansion modules "SIMAČ". "SIMAČ" modules are virtual elements that simulate the real elements and they are commonly used in industrial automation. Because of their cost they are integrated in extension kit as programmable modules. It also contains basic theoretical information about working with ATMEL AVR microcontrollers. Expansion modules with module development board and disc which will be loaded all the schemes, programs and technical documentation for individual districts will be attached to the thesis.
