This document describes the design and implementation of an Arduino-based radar system using an ultrasonic sensor. It discusses the sensor handling procedure, existing similar systems, the system block diagram, components used, performance, a demonstration of it working, and advantages of this system. The system allows an Arduino board to detect distances using ultrasonic pulses and transmit the data to an Android device over Bluetooth.

6. Sensor Handling Procedure
Based on datasheet requirements
1. Arduino sends a 10uS pulse via TRIG pin to sensor to start measuring.
• Sensor sends out a sonic burst
2. Arduino waits for reply on ECHO pin
3. Sensor ’s result is in a form of a pulse
• Time of pulse = time sound takes from emission to receipt

14. WORKING DEMO
1- Turn ON the Bluetooth on your android phone.
2- Connect the hardware to voltage between (7-12).
3- Open the RADAR application.
4- Establish the pair connection with the Bluetooth module .
5- Click on the start button and observe displaying of
distance angle and animations lines on your screen.
6- When done click on the stop button.

16. Conclusion
• Bluetooth communication is very useful and sufficient for
exchanging the data between Arduino and Android.
• ARDUINO class is the most important class of our system
design.
• Establishing the synchronization between sending and
receiving data between the two blocks is the most important
issue.
• As future work, use Wi-Fi connection between Arduino and
Android to allow monitoring through internet.
