Radar is a detection system that uses radio waves to determine the distance range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain, which is very important. It operates by transmitting electromagnetic energy toward objects, commonly referred to as targets, Besides determining the presence, location, and velocity of such objects, radar can sometimes obtain their size and shape as well. What distinguishes radar from optical and infrared sensing devices is its ability to detect faraway objects under adverse weather conditions and to determine their range, or distance, with precision. Radar underwent rapid development during the 1930s and ’40s to meet the needs of the military. It is still widely employed by the armed forces, where many technological advances have originated.

• Ultrasonic Sensor HC-SR04

• Servo Motor

• Arduino Board (UNO)

• Breadboard and Jump Wires

• Laptop

• Smart phone

• Card borads for covering

• Wires

• USB connector to computer

• Cutting knife

• Insulation Tape (Depends on you)

Please assemble your components on the breadboard according to the pictures given. Here are the steps before you assemble the wire.

First, you need to download the following programs:

1. Arduino
2. Processing

All you need for this Arduino Project is an Ultrasonic Sensor for detecting the objects, a small hobbyist Servo Motor for rotating the sensor, and an Arduino Board for controlling them. You can watch the following video or read the written tutorial below.

I made a cardboard stand for connecting the Ultrasonic sensor to the Servo motor. I folded it like it’s shown in the picture, glued it, and secured it to the servo motor using a screw-like this. Also, I attached a pin header on which I soldered 4 jumper wires for connecting the sensor. Finally, I taped the servo motor to the Arduino Board using an elastic band. I connected the Ultrasonic Sensor HC-SR04 to pins number 10 and 11 and the servo motor to pin number 12 on the Arduino Board.

Now, we are going to the step of coding to make this project works!

Here’s the Arduino Source Code with a description of each line of the code that you will be to download:

*Please download all the attches that I put on to make it all works (Funtional)
