How to make a Short range Radar using Arduino and Processing

Here’s a detailed guide on how to create a radar system using Arduino, a

In this project, we'll create a simple radar system using an Arduino, a servo motor, an ultrasonic sensor, and Processing software. This radar system will scan its surroundings and display the detected objects on a computer screen.

Materials Needed

- Arduino board (e.g., Arduino Uno)

- Servo motor

- Ultrasonic sensor (e.g., HC-SR04)

- Breadboard and jumper wires

- USB cable for Arduino

- Computer with Arduino IDE and Processing software installed

Step 1: Wiring the Components

1. Connect the Ultrasonic Sensor:

- VCC to Arduino 5V

- GND to Arduino GND

- Trig to Arduino digital pin 9

- Echo to Arduino digital pin 10

2. Connect the Servo Motor:

- VCC (usually red) to Arduino 5V

- GND (usually black or brown) to Arduino GND

- Signal (usually yellow or white) to Arduino digital pin 11

Step 2: Arduino Code

1. Open the Arduino IDE and create a new sketch.

2. Copy and paste the following code into the sketch:

3. Upload the code to your Arduino board.

4. Run the Processing sketch.

Step 3: Testing and Calibration

1. Place the radar system in an open area where it can scan for objects.

2. Power up the Arduino and make sure it is connected to the computer.

3. Run the Processing sketch to visualize the radar data.
