180 Degree Ultrasonic Radar Project with TFT LCD

Arduino UNO Ultrasonic Radar Detection Science Project Kit

Arduino UNO Ultrasonic Radar Detection Science Project Kit is an advanced DIY electronics and robotics learning project designed for students, STEM learners, and science fair participants in Bangladesh. This smart radar system uses the HC-SR04 Ultrasonic Sensor Module to detect nearby objects and display their direction and distance on a colorful 2.4 Inch TFT LCD Touch Display. The ultrasonic sensor rotates smoothly with the help of the SG92R 9g Micro Servo Motor, creating a real-time 180-degree radar scanning effect similar to modern radar systems.

This educational science project is highly suitable for school, college, and university students who want to learn practical Arduino programming, ultrasonic sensing, servo motor control, and display interfacing. The project also includes a 5V Active Buzzer that generates an alarm sound whenever an object is detected within 20cm distance. This feature makes the project more interactive and realistic for demonstrations and science exhibitions.

At Biggan Project, students in BD can explore modern electronics and robotics concepts through hands-on projects like this Arduino radar system. The project helps improve coding knowledge, circuit design understanding, problem-solving skills, and creativity. It is widely useful for science fairs, robotics workshops, engineering learning, and DIY electronics practice in Bangladesh.

The project body frame is built using durable 5MM PVC Plastic Board and organized with Nylon Cable Zip Ties, Flexible Project Wires, and Hot Glue Stick for a neat and professional appearance. The complete setup demonstrates how ultrasonic waves can measure distance and how radar-style scanning systems work in real life.
