Task 3 – Timer Programming with Arduino Nano

This project focuses on Timer/Counter programming, PWM generation, and ADC integration on the Arduino Nano (ATmega328P) without using Arduino libraries. All functionality is implemented at register level.

---

📌 Overview

The project demonstrates how to:

• Read analog input values using the ADC.
• Generate a PWM signal using timers to control a servo motor.
• Use voltage thresholds to trigger LED behaviors (blinking or dimming).
• Apply embedded C programming concepts directly on microcontroller registers.

---

⚡ Features

• Potentiometer input (0–5 V) → controls servo position (0°–180°).
• PWM output drives a servo motor.
• LED behavior:
  • Below 2.5 V → LED dims proportionally.
  • Above 2.5 V → LED blinks with 1s interval.
• No Arduino libraries used → all code works at hardware register level.

🚀 How to Run

1. Flash the C code to your Arduino Nano using AVR-GCC or Arduino IDE (register-level).
2. Connect the hardware as described.
3. Adjust the potentiometer and observe servo + LED behavior.
