The Arduino RADAR Model is a prototype radar system designed for detecting and measuring objects using an ultrasonic sensor. This project leverages an Arduino Uno, ultrasonic sensor, and servo motor ...

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 is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Smart Blind Stick using Arduino Circuit Diagram. The below circuit diagram shows the complete hardware wiring setup of the Arduino-based Smart Walking Stick for the Blind people, detailing how the ...

So I removed this servo and IR sensors and use 3 ultrasonic sensors. With ultrasonic sensors, you can measure distance and use that information to navigate and follow a human target. Here’s a general ...

This IoT-based smart bin project integrates an Arduino Uno R4 WiFi with ultrasonic sensors and a servo motor to automate waste disposal. The system uses proximity detection to open the lid and ...
