This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

Arduino Ultrasonic Sensor Code for Distance Measurement The complete code for this ultrasonic distance measurement project is given at the bottom of this page. In the code we read time by using ...

Create a smart blind stick using Arduino to help visually impaired individuals navigate safely. This DIY project uses an ultrasonic sensor, buzzer, and LED indicators to detect obstacles and provide ...

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 ...

The ultrasonic sensor with Arduino allows us to measure distances through ultrasound. It is very common to find this type of sensor in today’s cars. The objective is to show how we can build real ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...

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 ...
