Security and Privacy in IoT
Utěkal, Josef ; Dzurenda, Petr (referee) ; Malina, Lukáš (advisor)
The bachelor's thesis deals with the topic of security and privacy in the field of Internet of Things (IoT), for which resource constrained devices are typical. It is very important to find a suitable operating system that, in addition to low computational requirements, would also offer the desired functionality for these constrained IoT devices, such as real-time capabilities. OS RIOT seems to be the one for IoT. It enables you to run applications written in C language on any supported hardware -- in this bachelor's thesis specifically on Arduino Uno and Arduino Due. The thesis also describes several cryptographic libraries that are supported by OS RIOT. The aim is to implement selected cryptographic libraries and measure their computational and memory requirements on both Arduino devices. This is preceded by a theoretical and practical familiarization with OS RIOT, which is realized by creating the first project, and measuring the computational complexity of each cryptographic function of the WolfSSL library on the Raspberry Pi 4 Model B.

Laser diodes controller utilizing AVR microcontroller
Boštík, Jiří ; Šilhavý, Pavel (referee) ; Krajsa, Ondřej (advisor)
This thesis deals with the design and subsequent realization of laser diode control devices. The circuit will be able to control the diode with using a laser driver, via a computer network or via the display for control current values, setting of initial values and more. The device will be connected also with a SD card for saving of settings. In the theoretical part there are described individual components that are needed for functionality of the device. The practical part contains a block diagram, in which is described complete feature of the device, then a draft scheme with a description of all integrated circuits and important components. At the end of this work is described the software that controls the entire designed device.

Data system processing for memory card arrays
Janůš, Tomáš ; Háze, Jiří (referee) ; Fujcik, Lukáš (advisor)
The submitted thesis is concerned with a design of the multiplicator of memory cards. The basic focus of this thesis is the analysis of individual system components and adjustment of the existing arrangement. The analysis describes the existing arrangement of the multiplicator and deals with the potential of individual components. Adjustment of the existing arrangement includes definitions and processes of the individual multiplicator components design to the achievement of optimal performance. Operating of the multiplicator is fully controlled by a PC.

Quadcopter design and utilization with the use of Arduino Due
Majer, Dominik ; Olejár, Adam (referee) ; Krajsa, Ondřej (advisor)
This bachelor thesis is about design of usable prototype of quadrocopter using standard RC components, with Arduino Due control unit and gyroscope with MPU6050. Main goal is the fully functional prototype with feature for reduction of barriers collision possibility, using ultrasonic sensors. The first part of thesis is the description of each component and their cooperation. The second part describes final solution, flowchart, source code with problems arisen. Source code is written in programming language Arduino, which is based on Wiring language. Further the brief analysis of autonomous flight of quadrocopter is done, particulary with GPS module and possible brief design of this idea. Finally the analysis of basic options of telemetry transmission, such as GSM module, wi-fi, bluetooth, are analysed.

Design and realization of the pedal effect on Arduino platform
Gajarský, Tomáš ; Schimmel, Jiří (referee) ; Krajsa, Ondřej (advisor)
The topic of my bachelor’s thesis is the design and the construction of the pedal effect used by the Arduino Due, which is supplemented by the possibility of controlling through the internal web interface, which is mediated by the modul Arduino Ethernet Shield. The following effects are included: echo, tremolo, vibrato, chorus and flanger. For editing the guitar signal in order to interact with AD microcontroller converter, is used the input filter preamplifier circuit. In order of editing the output signal from Arduino is used summing and filtring output circuit for the guitar amplifier. The basic component for these circuits is operating amplifier OPA1644. The goal of this thesis was to create the proposal of the connection schemes, printed circuit board, the program code of the microcontroller, simple web page, as well as the construction and the measurement of the pedal effect.

Control of system with electric motors by CAN Bus
Hamřík, Petr ; Zuth, Daniel (referee) ; Huzlík, Rostislav (advisor)
The aim of this bachelor's thesis was to work the control of DC motors on already created stands using the CAN BUS. There is a research part in the thesis that deals with the control of DC motors. The DC motor simulation was created in MATLAB Simulink. The last part deals with the physical control of DC motors and the development of the user interface.

Robot control with model servo motors using image processing
Bielik, Adam ; Marada, Tomáš (referee) ; Huzlík, Rostislav (advisor)
This bachelor thesis focuses on the implementation of a program to control a robotic arm with model servo motors using image processing. The goal is to dynamically and accurately move the robotic arm using visual feedback obtained from the HuskyLens camera. The camera tracks the movement of an object and subsequently, the control program performs a kinematic calculation and moves the arm to the same position as the tracked object. The control program runs on the Arduino Due platform. The thesis also contains theoretical knowledge about servo motors and image processing, and also includes capabilities and basic technical specifications about the used hardware.

Design Of An Automatic Testbed For Evaluation Of The Influence Of The Environment On The Function Of Infrared Proximity Sensors
Radvanský, Martin
Proximity or obstacle detection is one of the everyday tasks to be solved in practice. Many sensors can be used for this purpose and usually is achieved by high detection accuracy. The problem occurs when the sensor is placed in an environment where the light conditions change, or one or more sensors are within the visibility range of the sensor. Manufacturers often do not provide all the necessary information about the behaviour of the sensor in such a disturbed environment in the product datasheets. This project is focused on the design of an automated testbed that will allow evaluation of the behaviour of the sensor during external interference. For testing purpose modulated visible and infrared radiation is used.
