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 ...
If you’re going outside (only for essential grocery runs, we hope) and you’re having trouble measuring the whole six feet apart from other people deal by eye, then [Guido Bonelli] has a solution for ...
