LED 3D object controlled by microcontroller
Gasper, Michal ; Němec, Zdeněk (referee) ; Holoubek, Tomáš (advisor)
The aim of this work is to design and produce a LED 3D object controlled by a microcontroller. The research part deals with the topic of microcontrollers, their history, architecture and components. Furthermore, this section describes the selection of a microcontroller and the resulting device for this work. In the practical part, the own design and solution is discussed in detail. Subsequently, the procedure for producing and writing the program code for controlling the LED 3D object is described. The program is written in C++ using the Arduino IDE and the FastLED library. The result of the work is a functional product that fulfills the assignment.

DMX 512 protocol analyzer for personal computer
Vahalík, Jiří ; Sysel, Petr (referee) ; Krajsa, Ondřej (advisor)
The bachelor thesis deals with the design of a DMX converter for a personal computer. The theoretical part summarizes the DMX, RDM and Art-Net protocols and other commonly used communication protocols used by microcontrollers. In the practical part, a device circuit is fabricated, which is subsequently processed as a printed circuit board. In the last part of the thesis, programs are designed to ensure the functionality of the whole converter.

Electronic chess
Kočka, Matúš ; Arm, Jakub (referee) ; Baštán, Ondřej (advisor)
This bachelor thesis is focused on function of capacitive sensors on a printed circuit board and a series of measurements from which it was possible to create a subsequent sensors for the chess board. It also deals with the CoreXY technique, according to which a design of a motion mechanism is made in the Siemens NX program, and its subsequent implementation. The device includes a microcontroller for which software is created to process data from sensors and control stepper motors.

Cryptographic coprocessors for IoT microcontrollers communication protection
Český, Michal ; Zeman, Václav (referee) ; Slavíček, Karel (advisor)
This bachelor thesis outlines the issue of how communication can be secured within the IoT. The microcontroller itself can also be used for this purpose, however, security will never be assured as it will be when using a hardware cryptographic co-processor. To generate the keys and certificate, the ATECC608B coprocessor is chosen which holds the necessary "secrets" used to secure the communication. As a demonstration of the cryptographic coprocessor functionality, the ESP32 microcontroller is connected to the AWS server where all the connections to the server are established using the cryptographic coprocessor.

Monitoring the living environment in the house
Dlugoš, Daniel ; Ježek, Michal (referee) ; Staněk, Kamil (advisor)
This work, tries to create a small, rechargeable and portable device that senses temperature, humidity, barometric pressure, dust particles, carbon dioxide and VOC concentration. The air quality monitor can reliably measure the physical quantities encountered in every indoor environment, evaluate them and display them to the user. The sensors, data storage module and OLED display are housed on a custom-made PCB board.

WiFi Attacks Using ESP32/8266
Stehlík, Richard ; Zobal, Lukáš (referee) ; Pluskal, Jan (advisor)
The goal of this thesis is an exploration of the possibilities of Espressif's ESP32 chips in combination with Espressif IoT Development Framework with intention of implementing well-known Wi-Fi attacks on this platform. In this work, multiple implementation proposals were done for deauthentication attack in two variants followed by WPA/WPA2 handshake capture, attack on PMKID, creation of rogue MitM access point, or brute-force attack on WPS PIN, and more. A universal penetration tool ESP32 Wi-Fi Penetration Tool was proposed and implemented, including deauthentication attacks with WPA/WPA2 handshake capture. This tool provides an easy way to configure and run malicious Wi-Fi attacks without any domain knowledge required from the user. The outcome of this work opens new attack vectors for the attacker, thanks to cheap, ultra-low powered, and lightweight ESP32 chips.

System with Model Servos
Švec, Radek ; Materna, Zdeněk (referee) ; Zemčík, Pavel (advisor)
The aim of this thesis was to study the ways of controlling hobby servos, and then to design and create small machine with hobby servos. The created machine is a six-legged walking robot - hexapod with 18 servos for movement. This robot can be remotely controlled using a mobile application for Android. Main control unit of the robot is ESP32 development board. The resulting hexapod is able to walk in all directions and rotate on spot with different walking gaits. It can also change its ground clearance and walking speed. The result of this thesis is a compact walking robot with basic functions, which is suitable for extensions, eg. adding a camera or measuring sensors.

A Gateway for Xiaomi Aqara Devices
Urbánek, Petr ; Koutenský, Michal (referee) ; Pluskal, Jan (advisor)
This paper deals with creating gateway for smart devices of brand Aqara. There is discussed ecosystem of Aqara devices, which are used for testing and reverse-engineering of communication. The Gateway is implemented on platform ESP32, which is using cc2530 system-on-chip. Newly made gateway makes a bridge between ZigBee and MQTT protocol, which provides connectivity betweeen sensors and actors from Aqara and Home Assistant. Thanks to the Home Assistant are all data about home safe and creating new home automatizations is a lot easier.
