Wireless IR sensor for space intrusion detection
Možný, Radek ; Krajsa, Ondřej (referee) ; Škorpil, Vladislav (advisor)
The bachelor thesis deals with design of wireless space breach detection sensor using sensor HC-SR501 and communication module SI4432. In thesis emphasis is on design of device with as low power consumption as possible using sleep modes of microprocessor Atmega328. Thesis includes desighn of temperature measurement, battery state measurement and subsequent broadcasting of gained information to receiving base station. Task of basae station is to evaluate information and among other things decide whether or not is guarded space breached. Two sensor network is further elaborated when sensors are sending periodical notification, person detection alarm, sensor manipulation alarm or warning about low battery state. Base station has regimes guarded and unguarded .

Control unit for positioning control of the experimental positional table
Fries, Lukáš ; Řezníček, Michal (referee) ; Adámek, Martin (advisor)
The work is devoted to the theoretical characteristics of the used components and its functioning. The main part is focused on practical design and build a functional device for control the position of the table, which is part of some unspecified workplace. Attention is mainly concentrated on the ATmega328, which is part of the module Arduino for control sub systems. The document describes a closer communication with the computer, which can be selected as a control element positioning apparatus. Change of position is provided by two stepper motors. The primary control was designed using buttons and the position information is the operator transmitted to the display. The whole concept is subject to the requirements on the reliability and accuracy with an emphasis on simple operation.

Microsolder controlled by microprocessor
Stavělík, Jiří ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This thesis describes circuit design and realization of the power and control system, which can hold constant temperature of solder tip. Control system is based on microcontroller Atmega328 of company Atmel, part of the work is the implementation and debugging control software. This solution allows to enter temperature by rotary encoder and to show the real temperature on LCD displey. This hardware also detects disconnection of solder tip, acoustic signals when the required temperature is reached and it holds last set temperature.

Mobile robot control system
Kalina, Michal ; Veselý, Libor (referee) ; Hynčica, Ondřej (advisor)
This thesis deals with building of two-wheeled mobile robot and consecutive creation of drivers and control for sensors, engines and controller design. The control is based on Arduino platform using ATmega328 processor. Firstly there is in this thesis recherche. Part of this thesis is modelling one where simulation model of our system is created, its linearization and then controller design. Further it contains description of the building robots body, description and functionallity of used engines, description of all sensors and detailed description of available printed circuit board. In the end there is software part where the engines control is described, operation of the sensors and functionallity of the controller. Result of this thesis is function application of controlling and operating of two-wheeled unstable mobile robot.

Electical stimulation of hand muscles
Hrozáň, Michal ; Balogh, Jaroslav (referee) ; Sekora, Jiří (advisor)
Bachelor thesis explains the effect of electrical stimulation on muscle and nerve fiber. It describes the process of stimulation and principles that apply while stimulation with electric current is applied. Specific muscle stimulation of thumb is described. Work provides a solid base of knowledge for understanding the processes that are present in stimulation of living tissue, which will be implemented in construction of stimulator. User graphical interface was created in Matlab. User can communicate using this program with microcontroller ATMega328 of Arduino Uno Board. Microcontroller processes received data and generates voltage on its output pins. An amplifier and electrode triggering system was designed as well.

Small path follower robot
Zacpal, Michal ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
This thesis describes the design and subsequent implementation of the control system for small path follower robot. On the introduction are presents the platform´s on which the system was built. In the next section are gradually introduced: A module for following the line (HW, SW), modul for control motors (HW, SW) and the control unit (HW, SW). Then is presents construction on which the system was tested. Finally, there were implemented two algorithms for tracking lines. Whole system, including the plug moduls is built on Atmel microcontrollers, and this ATmega8 and ATmega328. They are based on open - source platform Arduino, because they contain Arduino bootloader. Microcontrollers using I2C bus to communicate each other. Control unit is using to communicate with users LCD display and four buttons. For scanning a line is using five reflective optocoupler CNY70.

Microsolder controlled by microprocessor
Stavělík, J.
The aim of this thesis is to design microsolder control, which can hold constant temperature of solder tip and description of hardware and firmware implementation. This solution allows the same function like classical microsolders but you can connect modern solder tip with high heat capacity. Other requirements are: switching frequency should be above the audible frequency, rotary encoder for temperature adjust, LCD display.
