Microcontroller controlled timer
Heralecký, Lukáš ; Macháň, Ladislav (referee) ; Pavlík, Michal (advisor)
Bachelor thesis entitled "Microcontroller-controlledtimer" is focused on design and practical application created a device that will be capaje of depending on external dating of simple tasks. This paperdescribes the features and capabilities of the microcontroller ATmega162, the Operations and program services. There is also described several other components used such as RTC, LCD display, matrix keyboard, temperature and othersensors. The first part is devoted to the oretical introduction to microcontroller and used parts. In another part ofthe PCB design - suitable layout of components, connectors, location, solving problems in PCB design. Fortesting functions designed and manufactured equipment is made simple test PCB. The practical part ended custom programming microcontroller programming language C.

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.

Analog Signals Datalogger
Ščišľak, Tomáš ; Frýza, Tomáš (referee) ; Vyskočil, Pavel (advisor)
The subject of my bachelor’s thesis is construction of device, which provides measuring and digitally recording of analog signals. The first part of this thesis deals with an analysis of circuit properties and building the basic scheme. It was important to choose proper components available. Datalogger consists of integrated digital circuits, which provide fast and reliable communication path. Function of main unit performs microcontroller Atmega128. The realization of external modules for current sensing looks interresting, particularly implementation of Hall sensor ACS755, circuits HCPL and solution of their connection with the main board. Second part of this thesis is oriented on hardware and software realization.

Design of a complex automated system for aquarists
Hedvíček, Michal ; Kunz, Jan (referee) ; Uher, Miroslav (advisor)
Thesis deals with the theoretical design of an automatic control system for the aquarium and following simulation software environment Proteus ISIS. Due to simulation program can verify the behavior of the microprocessor in the specified functions, the correctness of electrical connections and errors in source code. The second part is analysis of commercial systems, their characteristics and applications. Apart from available commercial systems, there is a basic overview of commonly used peripherals in the aquarium, including their comparison and evaluation. Furthermore, the implementation of a complex system is done and the procedures and methods needed to set up the system are described. This topic also deals with cooling and reliability tests.

Ambulant Cardiac Monitor
Vaníček, Aleš ; Strašil, Ivo (referee) ; Číž, Radim (advisor)
This thesis describes the design and practical realization of a prototype mobile, battery-powered device that is able to periodically recording electrocardiogram and fotopletysmogram or blood pressure. Data from these periodic scanning is processed by microcontroller and stored on a memory card which is part of the proposed device. The device can be connected to a PC via USB like a virtual serial port.

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.
