This project is a mini radar system that uses sound waves to find objects and display their distance and direction on a small screen. The screen looks like a real radar and updates in real time to display the objects it detects within a semi-circle area.
The components required to develop this project are:
~ Arduino Nano/Uno
~ Micro servo motor
~ Ultrasonic sensor HC-SR04
~ HF Transceiver HC-012
~ TFT LCD
~ Resistors
~ 5V regulated power supply
~ Jumper wires
The step-by-step process of project building includes:
1. Upload source codes to the Arduino Nano boards in the transmitter and receiver.
2. Build the circuits according to the circuit diagrams.
3. Supply power to the transmitter and receiver.
4. Observe the output on the receiver display.
