Bluetooth cache
Franek, Miroslav ; Háze, Jiří (referee) ; Pavlík, Michal (advisor)
This thesis deals with bluetooth cache design for geocaching. It briefly describes what geocaching is and describes the bluetooth cache. It also describes the selection of hardware for realization, the design of circuit diagram and printed circuit board. Using a flowchart, it explains the firmware function and provides an application management manual for using an Android application for managing the cache. Presents the results of measuring cache consumption in individual modes. Finally, it proposes a solution to extend the cache life for a single charge.

Logger pulse from wattmeter
Severa, Pavel ; Kubásek, Radek (referee) ; Friedl, Martin (advisor)
Most electronic wattmeter contains output for processing information on the con- sumption of other devices. The aim of this semestral project is to create a suitable device for reading output from power meter, store this information on the removable medium in size and ability to integrate into the distribution cabinet. Among other things, will monitor and record mode cheaper electricity, known as night mode.)

Embedded System for Water Consumption Registration
Hajdík, Tomáš ; Bidlo, Michal (referee) ; Vašíček, Zdeněk (advisor)
The bachelor thesis deals with the issue of the status of wireless water meters.The goal is to design and implement a function prototype of the embedded system based on ESP8266 Wi-Fi module that is capable of registring the amount of water, consumed by individual users, via the wireless meter readout. Users can be identified by a contactless RFID card. Embedded system ensures its availability and makes data available to the administrator via Wi-Fi network. The administrator interacts with the system by using a mobile phone and an application running on the ESP8266. The work includes hardware design and software implementation using C++ programming language. The result is a functional prototype of the system that brings new possibilities in the sphere of wireless meter readers because it does not require unaffordable and highly specialized appliances for recording consumption, is accessible from the mobile phone and thus extends the market to ordinary consumers as well.

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.

Communication with external devices by I2C bus
Prax, Jakub ; Šebesta, Jiří (referee) ; Frýza, Tomáš (advisor)
This diploma paper deals with the data bus line I2C and a supportive demonstration tool for the subject Microprocessor technology taught at the Radioelectronics faculty. The data bus line I2C is convenient when short-distance data transmission with restricted spatial possibilities is required but high velocity of data transmission is not necessary. The tool is compiled in such a way that enables it to also perform other tasks apart from those dealing with the I2C data bus line. The data bus line in the tool is utilized for transmission of date, time, temperature, data for the D/A converter, data from and to the EEPROM memory and data to 16 bits expander.
