Digital AM / FM transmitter
Kováč, Marek ; Strašil, Ivo (referee) ; Pavelka, Ondřej (advisor)
This master thesis is focused on the theoretical description and practical implementation of software defined transmitter. The main aim of this thesis was made the prototype of software defined transmitter in FM band. Theoretical part is determined to description of basic parts of equipment and working principles to understand the basic principle of digital transmitters and define the appropriate component base for construction. Discussed are used types of A/D and D/A converters, blocks of digital signal processing and the roles, which these components performs. The second part is focused practical. Specified are suitable types of components and block diagram is proposed for following electrical connection and printed circuit board in Eagle program as a plug-in modul for developmental platform Arduino. The main point is program, which sets and controls the transmitter. Next important part is impedance match and antenna tuning, which is explain in practical part of thesis. The result is prototype of software defined transmitter compatible with Arduino Uno platform.

Automated Shooting Range for Air Pistols
Radvanský, M.
This work deals with the design and manufacture of the device, which is used as a shooting range to practice shooting with an air gun. The device is controlled by the Arduino MEGA and could be connect to any number of smart targets. It is designed to be easily portable, comfortable to use, to enable multiple modes of activity and support several of shooters. The secondary aim is also to ensure the attractiveness of the firing for shooters.

Robot
Flek, O.
The objective of this paper is to design and produce a robot based on a four wheel chassis equipped with a robotic arm capable of manipulating small objects. The robot should be able to operate in an autonomous mode controlled by a microcontroller and in a mode controlled wirelessly by an operator in real time. Precision and accuracy of the robotic arm should be sufficient for the collection of small objects, such as syringes and needles. The entire robot should be easy to operate user-friendly controls so as to minimize training for other users. The machine construction should be easily disassembleable - allowing easy adjustment or replacement of any of its parts.

Board computer with GPS module for motorbike
Kaláb, Lukáš ; Vyskočil, Pavel (referee) ; Brančík, Lubomír (advisor)
This thesis describes the design and subsequent construction of a board computer for a motorbike, using a GPS module. Vehicle speed, distance travelled and the motor's rotations (RPM) are among the basic elements that are measured and shown. Furthermore, the mechanism allows one to measure and show the average consumption, the temperature of the surrounding environment as well as the motor's temperature, battery voltage, current time, and, with the help of the GPS module, the current GPS location of the vehicle, including altitude. The vehicle's entire journey can be saved to the memory card for further processing in a PC.

Digital Signal Processor based Baby Cry Detector
Sobotková, Šárka ; Rozman, Jiří (referee) ; Sekora, Jiří (advisor)
The thesis discusses the baby cry. Processing of literary research in dealing with children crying and processing of audio signals. Based on information gathered propose an algorithm for detecting child's cry, which was verified using Matlab programming environment. Based on the identified parameters of the input signals and the proposed algorithms was selected appropriate digital signal processor. The hardware device was realized to detect and initialize the child crying, and its functionality has been verified in the recorded sound recordings child crying.

Control of Music Equipment with Non-Electric Sensors Using MIDI Protocol
Vlach, Miloš ; Číž, Radim (referee) ; Schimmel, Jiří (advisor)
The goal of this Master’s thesis is to create a device that is able to control MIDI musical electronics, via use of non-electrical sensors as un-usual control elements and module Arduino Diecimila used as the processing element. This thesis is dealing with this given problem from a complex point of view, from design to actual realisation of the device. In the process of the thesis the solution for an optical proximity sensor and for resistance weight sensor is delivered. For both of them the adjustments circuitry is designed including interfaces, and further on it is constructed on PCB board. Then, control software, which processes the input sensor signal into a stream of MIDI data, which is sent to the computer as a slave device, is developed. The runtime of the program and the behaviour of MIDI elements can be controlled with a sub-protocol based on MIDI SysEx messages.

Standuino
Merta, Ondřej ; Boleslavsky, Andrej (referee) ; Šedivá, Barbora (advisor)
Standuino is the inovative force in hand-made electronic music and open source hardware as well as theoretically and historically driven movement that results in artworks, bands, workshops, happenings and writings. Standuino started as a clone board of popular Arduino but adapted to even more DIY approach of eastern region (=bastl). With this powerful tool it became part of many art installations and enabled our research team to build prototypes of many different devices most importantly musical instruments. The whole concept of Standuino is inspired and covered by the story of a pioneer of media art – Standa Filip.

Present-day Programming Method of Microcontroller
Medla, Eduard ; Matyáš, Pavel (referee) ; Zuth, Daniel (advisor)
This bachelor thesis is dedicated to modern methods of programming microcontrollers. In this work are examined some programming languages, various programming environments and graphic editors. In every methods of programming are explained their advantages and disadvantages. Here are two examined methods of loading program to microcontroller, so called flashing. Choosed method is programming language C, which was used to programme two-state regulator with hysteresis in environment AVR Studio 6.2.

The robotic manipulator for the Hanoi towers solving
Spáčil, Radim ; Zuth, Daniel (referee) ; Marada, Tomáš (advisor)
Main theme of the bachelor’s thesis is to design and manufacture a manipulator which can solve mathematic issue called the Hanoi towers. Main goal is to make a machine, which will automatically solve the above mentioned mathematic issue and will server for institute of automation and informatics for presentational purposes. This thesis contains of choosing the proper mechanical solution. Chosen solution will be afterwards design in Autodesk Inventor 2015 programme. Unique components which cannot be bought will be made by using 3D printer and machine will be assembled and then control by micro controller Arduino Mega 2560.
