This schematic was designed using EasyEDA and shows the complete connection setup of the ultrasonic sensor (HC-SR04) with the Arduino UNO and two LEDs. It includes pin mappings, power rails, and ...

This project combines a joystick, servo motor, ultrasonic sensor, two LEDs, and a buzzer to create an interactive object detection system. The joystick is used to rotate the servo motor left and right ...

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 ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...

Abstract: Vehicle over-speed detection and accident-avoidance system is an Internet of Things (IoT) based system which collects data via sensors such as ultrasonic sensors and alerts the driver. The ...
