This repository contains Arduino-based embedded systems projects developed using C/C++, electronic components, sensors, actuators, and microcontroller peripherals.
The projects demonstrate practical implementation of:
- Digital and analog input processing
- Sensor interfacing
- ADC-based measurement
- PWM-based control
- Serial communication
- Timer and interrupt handling
- Motor and actuator control
- Embedded automation
- Hardware–software integration
- Circuit prototyping and testing
The repository reflects my practical foundation in embedded systems, electronics, microcontroller programming, industrial automation, and control-system development.
The main objectives of this repository are to:
- Develop embedded applications using Arduino-compatible microcontrollers.
- Interface sensors, switches, displays, motors, and actuators.
- Process analog and digital signals.
- Implement ADC and PWM-based control functions.
- Develop modular and understandable embedded C/C++ code.
- Apply timers, interrupts, and non-blocking control methods.
- Test hardware and software behavior using serial monitoring and simulation.
- Connect embedded-system concepts with automation, signal processing, and engineering applications.
