An Arduino-based radar system using ultrasonic sensor, servo motor and ... This project creates a radar-like object detection system using: HC-SR04 Ultrasonic Sensor; SG90 ... sensor; Radar-style GUI ...

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.

This ultrasonic radar project is from [mircemk] who uses a small ultrasonic distance sensor attached to a rotating platform. A motor rotates it around a 180-degree field-of-view and an Arduino ...

This project is an autonomous robotic car built using an Arduino microcontroller. The car uses an HC-SR04 ultrasonic sensor for obstacle detection, an L293D motor driver shield to control four DC ...

In this mode, you can interface the HC-SR04 ultrasonic ping sensor with a servo motor and the main board (Only some reward tiers include the extra servo motor PCB and servo motor kit).

Arduino Uno – Powered Parking Guidance System with Ultrasonic Sensors" is a smart and innovative solution for simplifying the parking process in crowded urban environments. This paper leverages the ...
