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.

Electronic controlled glow for water hookah
Rumíšek, Tomáš ; Šebesta, Jiří (referee) ; Fedra, Zbyněk (advisor)
This bachelor thesis deals with the substitution of a standard charcoal heating system for an electronically-controlled heating element in a hookah. The heating element temperature is regulated by the Atmel microprocessor, depending on the temperature specified by an user. The user can adjust the desired temperature on a control panel, where also the actual temperature of the heating element will be displayed.

Adjustable source feeded and controlled by USB bus
Staněk, Miroslav ; Frýza, Tomáš (referee) ; Kolouch, Jaromír (advisor)
The aim of this bachelor’s thesis is concept and realization of voltage source which is controlled and feeded by Universal Serial Bus. There will be presented whole design, execution, development progress and finalization of this project in the following text. This source must boost and buck standard voltage from USB. So it will be necessary using two source lines. Microcontroller of AVR family will be used in the direct part of this adjustable source. Into this microcontroller will be embedded USB interface by the software solution. The microcontroller isn‘t used only for communication with PC by the computer programme, but it is also used for switching the source lines by the PWM modulation. According to the minimum output voltage scale (0 – 15 V) this source is useful for a wide spectrum of low- power devices. This equipment could be helpful together with laptop to charging devices (cell phone, camera, pocket osciloscope etc.), which are carried with notebook for doing outdoor activities and measurements.

Automated environmental support system for aquarium
Slavotínek, Jan ; Honec, Peter (referee) ; Petyovský, Petr (advisor)
The thesis is devoted to analysis of parameters and processes in aquarium, in order to design system for control, regulation and monitoring the most important of them. In theoretical part of thesis are defined terms and basic knowledge necessary for successful analysis, some of them are marginally reaching into different science discipline (biology, zoology, engineering, etc.). The thesis contains a part focused on analysis of common operation and requirements connected with prospering aquarium. In this part are determined common ranges of values, limitations and requirements on safety operation of system, if necessary. Following chapters of thesis are devoted to design hardware and software solution of particular system, ensuring control, regulation and monitoring of variables and processes determined as critical.

Industrial programmer Atmel AVR microcontrollers
Gryžboň, Jan ; Hanák, Pavel (referee) ; Pavelka, Ondřej (advisor)
The aim of this thesis is to design and implement an industrial programmer AVR microcontrollers from Atmel. The first section provides the theoretical knowledge of the AVR microcontroller. Furthermore, comparison of methods for programming the microcontroller and the selected method is an analysis of the speed of programming. The following is the entire design of industrial programmer which is implemented in the programming environment Eagle. In the penultimate part of the proposal is designed PCB. The final section is devoted to the revival of the programmer and programming.
