Скачать или смотреть ESP32 + Ultrasonic Sensor + LED + Buzzer | DIY Distance Alarm in Wokwi

In this tutorial, we’ll build a simple yet powerful project using the ESP32, an ultrasonic sensor, an LED, and a buzzer in the Wokwi simulator. You’ll learn how to measure distance, trigger an LED warning, and sound a buzzer when an object comes too close. This experiment demonstrates how ultrasonic sensors are used in real-world applications such as home security alarms, automatic doors, parking assist systems, and obstacle detection for the visually impaired.

By the end of this video, you’ll not only understand how to wire and program the circuit, but also see practical scenarios where you can apply ultrasonic sensors in IoT and automation projects.
