Ultrasonic Radar with Arduino

Build Your Own Ultrasonic Radar with Arduino

Create a fully functional Ultrasonic Radar using an Arduino UNO, Ultrasonic Sensor HC-SR04, and SG90 Micro Servo Motor. This exciting project combines Arduino programming with hardware integration, making it perfect for hobbyists and students.

Components Needed

All components can be easily found on aryabot.in, ensuring high-quality products for your project:

  1. SG90 Micro Servo Motor: Enables precise rotation for the ultrasonic sensor scanning.
  2. Ultrasonic Sensor HC-SR04: Detects and measures distances to objects within its range.
  3. Arduino UNO: The microcontroller responsible for controlling the entire radar system.

Steps to Build

  1. Connect the Ultrasonic Sensor HC-SR04:
    • VCC → 5V
    • GND → GND
    • TRIG → Pin 2
    • ECHO → Pin 3
  2. Set Up the SG90 Micro Servo Motor:
    • RED wire → 5V
    • BROWN wire → GND
    • ORANGE wire → Pin 4
  3. Mount the Ultrasonic Sensor on the Servo Motor to enable rotational scanning.
  4. Write the Code: Use Arduino IDE to program the radar’s scanning and object-detection logic.
  5. Display the Radar Output: Visualize the radar’s output on a Processing IDE interface or a compatible display module.
