Hi ! I am years old and I am a Junior Firmware Developer. I am a responsible person and eager to learn new things
I'm passionate about ski and cycling. I spent my spare time, most of the time, riding my bike on the mountains around Brașov.
I made this website in 2019 to get my certification in computer science in high school.
I made this website to present my drone footages. It's an one page webiste made with Bootstrap5.
In this project, irrigation is automatic, using some random soil humidity values. You can also activate the 5V water pump using Blynk App or with the push button from the project case.
This project was realised during the practice organised by the Preh Company fom Brașov.
This hardware project was created to be used in implementing the control of a DC motor via PWM signal, in the context of bare-metal programming. The circuit contains a discrete H-bridge, with transistors, protection diodes and bias resistors, allowing the control of the direction and speed of the motor via direct digital signals from the microcontroller.
This project was developed in a University Course. I worked in a team and my roles were team leader, GUI Developer using Embedded Wizard and Middleware Developer using a STM32 Discovery Kit.
This project consists of a dual power supply, capable of providing both positive and negative voltage, adjustable between 1.25V and approximately 30V. The source uses adjustable voltage regulators (LM317 for the positive branch and LM337 for the negative), allowing the supply of analog or digital circuits that require symmetrical voltages. The adjustment is made using potentiometers, and the voltage values are displayed on an integrated digital voltmeter.
This project presents the design, implementation, and experimental validation of a monitoring and testing system for communication protocols over the RS485 interface. The system integrates both hardware and software components to analyze data exchanged between connected devices in real time. The firmware was designed to be synchronized with the communication flow, ensuring accurate data capture and reliable operation. The system enables multiple functionalities, including frame visualization, measuring the time interval between messages sent by the master device, transmitting test messages during idle periods, and detecting malfunctions of the slave device. Communication with external systems is achieved via the CAN interface, allowing data logging and further analysis. Extensive testing was conducted, including in electromagnetically noisy environments, to validate the system’s performance and reliability. The results confirm its effectiveness in monitoring RS485 communications and diagnosing potential issues in industrial applications.
This dissertation presents a comparative analysis of the Thread and Zigbee communication protocols for Internet of Things (IoT) applications. The study evaluates performance metrics such as latency, data rate and range. Practical experiments were conducted on embedded platforms including STM32WB and ESP32-H2, and results were supported by an in-depth review of IEEE research articles. The project highlights the trade-offs between the two protocols and their suitability for various smart networking scenarios.
