Hire the Best Arduino Experts

I’m an Embedded Systems Engineer specializing in Firmware development, with nearly 10 years of experience in the field. I have extensive experience with the following microcontroller families: PIC16F/18F, STM32 and other ARM Cortex-based MCUs, ATmega, ATtiny, SAMD—and most recently, the ESP32 family for IoT devices. 1️⃣My strongest skill is an in-depth knowledge of MCU internal architecture and operating principles: ⚡Memory organization, ⚡Instruction sets and execution, ⚡Device configuration, ⚡Watchdogs, ⚡Interrupt services (including multiple-interrupt handling), and ⚡Peripheral management. I’ve worked with virtually all standard peripherals found on modern MCUs— 🚀 Precise Timer usage; 🚀 PWM drivers; 🚀 Capture-Compare units; 🚀 ADCs; DACs; and 🚀 Serial Communications (I²C, SPI, USART, I²S). Less common peripherals I’ve tackled include the STM32 🔹AES encryption accelerator; the PIC16F’s 🔹NCO and 🔹logic-gate features; the PIC18F 🔹USB module; and the ESP32’s 🔹PDM and 🔹I²S interfaces and various other specialized modules. ➡️This deep understanding of MCU internals lets me write high-quality code with very few bugs from the outset, and it makes debugging far faster in later development stages. 2️⃣Hardware integration I deliver seamless, efficient hardware integration for: 🔹Sensors (analog and digital: temperature, humidity, light, voltage) using SPI, I²C, 1-Wire, USART, etc. 🔹Input devices from simple buttons, keypads, potentiometers, and rotary encoders to touchpads and sliders. 🔹Output devices including LCDs (various sizes), OLEDs, addressable LEDs, 7-segment displays, touchscreens, and more. I go beyond plain text and primitives, 🎨crafting eye-catching UIs with attractive fonts, colors, images, and animations whenever possible. 3️⃣I can develop—and maintain—a complete embedded-system firmware from start to finish, ensuring it’s easily maintainable by future engineers. When your embedded system is part of a larger ecosystem (e.g., IoT devices or desktop/mobile-controlled systems), I’ve implemented higher-level protocols like USB, Bluetooth/BLE, HTTP, and MQTT. I write clean, well-documented firmware APIs that integrate effortlessly into any larger system. 4️⃣An invaluable skill I bring is the ability to emulate missing peripherals entirely in software—avoiding the time, cost, and chaos of a board redesign. When hardware truly falls short, I step in to replicate its functionality in firmware, keeping development on schedule and often yielding more flexible, upgradable solutions. Of course, this isn’t a cure-all: some features simply demand a hardware revision. 5️⃣When required, I code “close to the metal” in low-level C or even Assembly. I’ve worked on legacy chips (e.g., Intel 8051 and 6502 derivatives) where assembly-only firmware was essential. 6️⃣Circuit and PCB design Although my primary focus is firmware, I hold an electronics engineering degree and am proficient at reading schematics. I collaborate smoothly with hardware designers and can propose elementary hardware solutions when needed. 7️⃣I’m a thorough researcher who always studies documentation carefully before drawing conclusions. While this can slow initial progress, it pays off with faster, more reliable development later on. 8️⃣Other skills and interests Windows desktop app development (WinForms) Web scraping (I’ve built sports-results scrapers) Retro game development (I’ve completed a SNES game) You can find many of my projects—console utilities, ASCII-art games, web scrapers, and more—on my GitHub page.

I'm Luka, an up-and-coming physicist, computer scientist, and tech enthusiast based in Belgrade, Serbia. While working on my Bachelor's in Computer Physics, I also like to do all kinds of freelance work here as well - mainly writing, but I'm also open to projects relating to computer or theoretical physics, data science, or programming. I had initially enrolled for a Theoretical and Experimental Physics diploma, but switched to Computer Physics as my career plans and interests shifted. However, I still have a lot of skill and knowledge related to both tech and science, and I love writing about both of those topics. In addition, I've spent a large amount of my work history here writing about various unrelated topics too - from travel and crypto to fitness and teaching. Overall I can deliver high-quality, SEO friendly and well-researched content on any topic, with a slight preference for tech and physics. Every single word I type is my own, and I do not use AI in my workflow, unless required by my clients. I also have a strong work history in education and teaching, having spent more than 6 years as a teacher, mentor, and coordinator in the fields of Astronomy, STEM, and Electronics, at the Petnica research center. I'm willing to provide tutoring services tailored to your specific needs on any of the fields I'm good at - be it LaTeX, Python, Mathematics, English, Arduino, Matlab, Computer Hardware, Electrodynamics or anything else related to my field. These tutorials can be live sessions, provided as written content, or hybrid. Following the nerd culture stereotype, I also quite enjoy reading fantasy and philosophy, playing and creating both board and video games, as well as running RPG campaigns. I can provide my skills on related projects in creative writing, story/quest/campaign structure development, or anything in between. Apart from those hobbies, I also enjoy bouldering, historical fencing and gardening, although I'm but a novice at the latter.
