The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy ...

Promoted as low-cost components, the Virtu and Virtu18 ultrasonic sensors are now available with analog outputs. Both are dual-mount, barrel-style sensors with a sensing range from 50 mm to 508 mm ...

The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy ...

How the Arduino ultrasonic sensor actually works. To measure distances with Arduino we can do it in different ways. There is the infrared sensor, which uses the properties of light to calculate ...

Here is the simple Arduino and 3 Ultrasonic sensor based Human-following robot code that you can use for your project. This code reads the distances from three ultrasonic sensors (‘frontDistance’, ...

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.

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 ...

For analog sensors, ensure compatibility with Arduino's analog input pins, considering factors like voltage range and resolution. Digital sensors should match Arduino's digital input/output pins ...

We can either use the AO pin as an output for analog reading or the DO pin as an output for digital readout. The Sound sensor pinout is as follows: VCC is the power supply pin of the Sound Sensor that ...

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.
