Embedded systems developer specializing in C/C++ firmware for AVR and Arduino microcontrollers.
I build modular libraries, sensor interfaces, and communication protocols for real-world embedded projects.
- Embedded C / C++
- AVR / Arduino (ATmega328P, Arduino Nano/Uno)
- Communication protocols: I²C, SPI, USART
- Sensor interfacing: HC-SR04, LCD modules (16×2 & 20×4)
- Low-power design & RTC-based wake-up
- Firmware architecture and modular library design
- LCD-1602 – 16×2 character LCD library
- LCD-2004 – 20×4 LCD library
- ADC-battery-SOC – Battery state-of-charge monitoring
- I2C-communication – Master-slave I2C example
- HC-SR04 – Ultrasonic sensor driver with LCD display
