Ultrasonic Sensor Measurement: The HC-SR04 ultrasonic sensor measures the distance to an object by emitting a sound wave and measuring the time it takes for the echo to return. The sensor is connected ...

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 ...

Hardware system consist of basically 3 components named as Arduino, servo-motor, and ultra-sonic sensor. Ultrasonic sensor is mounded upon a servo motor which helps it to move and provide it a turning ...

The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...

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 ...

Inside the 3D printed enclosure is an Arduino Pro Mini, a HC-SR04 ultrasonic sensor, and a 1602 serial LCD. Once the gadget has been mounted in the proper position and activated, ...

HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using this sensor. Device is very simple and ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...
