Mar 16, 2023 · The HC-SR04 ultrasonic sensor-controlled piezoelectric buzzer is a versatile and cost-effective system that can be used in a variety of applications such as object detection, obstacle avoidance, and proximity sensing.

This is a quick and easy guide on how to make a proximity alarm using a HC-SR04 Ultrasonic sensor, Arduino UNO, Arduino breadboard, and a 6V DC buzzer. This sensor will beep as an object move closer. The photo above is the setup of the board. Connect the jumper wires as follows to connect the breadboard and Arduino UNO together:

Mar 19, 2024 · But here, we present the best five Arduino ultrasonic sensor projects. Keeping your private things safe from intruders can be a challenging job. But with this Intruder Alarm project, it is easy to keep your accessories safe. The circuit makes a sound via a buzzer when an object comes near the sensor.

Oct 28, 2017 · Arduino Ultrasonic Sensor HC-SR04 Full Build and Code I'm really excited to show you my first real standalone Arduino project. An ultrasonic distance indicator with LED lights and a buzzer.

Basically we have an Ultrasonic sensor that measures the distance and the LED’s bar graph will light up according to our distance from the sensor and as we get closer the buzzer beeps in a different way. This circuit can work as a parking sensor! It's easy and cheap. Check my website for more electronic projects and information. Thanks!
