Arduino Project 52- Parking sensor using ultrasonic range finder HC-SR04

BuildCircuit5 years ago4 years ago01 mins

This is yet another ultrasonic range finder project using Arduino. We have done several similar projects in the past. It allows us to control a buzzer based on the distance detected by an HC-SR04 sensor, making it sound with a frequency proportional to the distance from an obstacle. 🛠️ Dive into our collection of DIY…
