Internet of Things in Practice
Zajíček, Milan
Prerequisite of working with microcontrollers is understanding the basic principles of their communication with the environment and possible ways of their programming. The ESP8266 microcontroller is one of the most popular chips used in Internet of things applications. Wemos D1 mini is one of development platforms behind the ESP8266,which allows direct communication with the PC via a USB port and has plenty of input and output peripherals to build simple IoT devices. The ArduinoIde development environment is used for programming. The thermostatic switch is made as a result of this tutorial.

Digital filtration in 8-bit microcontrollers
Záplata, Filip ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
The aim of my bachelor’s thesis is a digital filtration using the 8-bit processors. Digital filters are in use a lot and gradually outdoing analog equivalents. Their advantages are indisputable, but computing still inhibits bigger progress. Generally used microcontrollers do not have very powerfull core, so there is effort to apply as bright as possible algorithms. Program code can be written in C language or assembler eventually is possible to combine both languages. The task is to make a library of functions based on some powerfull algorithms for filtering. Testing those libraries and comparing their useability focused on maximal speed and universality of use and review ways of programming.

EMD instruments and electromagnetic mmunity
Mikula, Dalibor ; Buchta,, zdeněk (referee) ; Havlíková, Marie (advisor)
The work deals with implantable devices and possibilities of interference of elektromagnetic field. At first, the electromagnetic compatibility is discussed. Basic terms are explained, followed by insisting on resources of possible distrurbing of implantable devices and standards dealing with this issue. Furthermore, short chapter about devices affecting function of implantable devices is introduced. It means devices which patients with implantable devices may meet in common life, as well as devices used in common life, also devices used jn medical environment. In the next part, measuring process of electromamagnetic effect in working compartment of FN Brno magnetotheraphy and elektrotheraphy is devised. There is a concept of measuring card thanks to which impulses of implantable devices are measured. Finally, a description of measuring on implantable devices in FN Brno. MIKULA, D. EMD instruments and electromagnetic immunity. Brno, 2009. 74 s. Master’s thesis in Brno University of technology on faculty of elektrical engeenerig and communication. Supervisor Ing. Marie Havlíková , Ph.D.

Multimedial education interface for programming and debugging software for AVR microcontrollers
Šrajla, Josef ; Sajdl, Ondřej (referee) ; Pavlík, Michal (advisor)
Diploma thesis is concerned with programming of AVR microprocessors. Main task was development of compact environment where user can learn methods necessary for successful programming of microprocessor. It was necessary to make an application enabling interactive simulation of processor to reach this goal. User-friendly control, simplicity and low hardware demands are main advantages of this application. Only computer with internet connection is demanded. Complicated installation, usual for similar products, is avoided.

Building Kit and sample tasks for the primary school with Atmel AVR MCUs
BUŠEK, Vojtěch
This thesis describes the design and implementation of a building kit suitable for teaching how to work with Atmel AVR single-chip computer and its peripheral circuits. Included in the thesis are drafts of electrical schematics of each individual module of the building kit, drawings of the PCBs as well as propositions for sample tasks used in teaching this subject. These further encompass methodological and work papers. Due to it's simplicity and clarity the Bascom AVR was chosen as the programming language for all applications.

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.

Easy Programmable Logic Controller
VLNA, Martin
The objective of the work {\clqq}Easy Programmable Logic Controller`` was to create an easy system which contains some digital inputs and outputs, under which it will be possible to program the basic logical operations with the help of the display, keyboard and system interface. The point is to put near to the industrial system which is called Programmable Logic Controller (PLC).
