Arduino Nano H C-SR04 ultrasonic sensor SG90 servo motor 1.8″ ST7735 Display (or equivalent) Soldering kit Screwdriver set 9V battery and connector Electrical wires and soldering gear.

Unlike traditional radar systems that solely rely on waves, this setup introduces the use of ultrasonic signals, resulting in a significant change. The setup includes an Arduino board that is ...

A complete home automation system developed on ESP32 microcontroller using freeRTOS. The system is controlled wirelessly via Bluetooth with an android app developed using MIT App Inventor. This ...

The receiver displays the distance and angle of the object on the TFT LCD and shows the radar dial and scanning process animation. The transmitter uses an ultrasonic distance measurement (UDM) sensor ...

You can watch a video of distance measurement (to a human) in the video below including a demo that shows it working through a wall, something that’s not possible with ultrasonic or ToF sensors.

Radar technology has been a cornerstone of numerous applications, from aviation to meteorology, offering invaluable capabilities for object detection and tracking. Traditional radar systems, while ...

Arduino Radar Visualization An Arduino project for visualizing distance measurements using an ultrasonic sensor and servo motor, with a Processing sketch for real-time graphical representation.

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.
