🧹 Desktop Cleaner

This project is an Arduino-based desktop cleaner robot equipped with an ultrasonic sensor for obstacle detection, a DC motor driver for movement, and an OLED display for real-time distance monitoring.

---

📌 Features

• Displays "DESKTOP CLEANER" on an OLED screen at startup.
• Uses HC-SR04 Ultrasonic Sensor for measuring distance.
• DC motor control with direction pins for cleaning action.
• Real-time distance feedback on OLED and Serial Monitor.
• Stops when objects are far; activates motor when close.

⚙️ Pin Configuration

• Motor Control

  • motor1pin1 → Pin 2
  • motor1pin2 → Pin 3

• Ultrasonic Sensor

  • TrigPin → Pin 9
  • EchoPin → Pin 8

• OLED Display

  • I2C Communication (SDA, SCL) at address 0x3C

🚀 Code Explanation

1. Initializes the OLED display and shows "DESKTOP CLEANER".
2. Measures distance using the HC-SR04 ultrasonic sensor.
3. Displays distance in cm on OLED and Serial Monitor.
4. If distance ≤ 15 cm → motor runs forward ("LOW DISTANCE").
5. If distance > 15 cm → motor stops ("HIGH DISTANCE").

📊 Example Output

• OLED Display
  DESKTOP CLEANER Distance: 12 cm

• Serial Monitor
  Distance: 12 cm LOW DISTANCE
