That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

This sensor is available in multiple variants and I’ll be using the ‘HC-SR05’ variant. It can easily detect range between 2 to 450 cm and has 5 different pins, out of which, we don’t need ...

While Arduino and its libraries are the quickest way to interface with a sensor and blink an LED, sometimes you shouldn’t have to write and compile code to do something exceptionally simple. … ...
