About this Gig
Need a reliable C or C++ developer for your microcontroller project? You're in the right place.
Hi, Im Arthur a Mechatronics Engineer and Embedded Systems developer specializing in C/C++ programming, microcontroller logic, sensor integration, PCB design, and hardware prototyping.
I help people and businesses turn ideas into working embedded systems, from simple Arduino scripts to full custom firmware for AVR, ESP32, ARM boards, and custom PCBs.
What I can build for you:
- Microcontroller programming (C or C++)
- Arduino, ESP32, ESP8266, STM32, ATmega, RP2040
- UART, I2C, SPI, PWM, ADC, Timers, Interrupts
- Sensor & module integration (IMU, OLED, NeoPixel, motors, etc.)
- Firmware for custom PCBs
- State machines, debouncing, real-time logic
- Hardware troubleshooting and debugging
Why work with me?
- Mechatronics Engineer (hardware + software integration)
- Clear communication and easy collaboration
- I explain everything so you always understand what youre getting
- Professional documentation and clean code
- I can support you from idea code hardware test
Lets build your project, your prototype, or your full embedded system with precision and speed.
