Learn how to interface a microcontroller with an ultrasonic sensor in four steps. Choose your components, wire them, write the code, and test your interface.

The Arduino keeps on processing the data from the ultrasonic sensor, and it quickly triggers the Audio alert when it detects something nearby. Here, you’ll learn how to interface the ultrasonic sensor ...

ultrasonic-distance-led Arduino + HC-SR04 distance-based LED feedback system 📸 Project Media 🔌 Circuit Schematic This schematic was designed using EasyEDA and shows the complete connection setup of ...

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 ...

One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a Linux computer. The end result is a virtual touchscreen that can be made at home.
