By reading different values from the sensor, we can detect if is it light , dark or a value between them. Another element that we are going to use on this experiment is Piezo Buzzer. So what is it ?

An Arduino Nano-based system that uses an eye blink sensor to detect driver drowsiness and sounds a buzzer to alert them. A simple, low-cost solution to help prevent drowsiness-related accidents.

As we know that not all cars come with parking sensors. If we want to install an external parking sensor, it costs a lot of money. But luckily we can make a low-cost parking sensor by using Arduino.

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.

In this blog, we will learn about how to interface a Passive Infrared sensor (PIR Sensor) or motion sensor with an Arduino. We will also learn about how this sensor works and different parts of it. So ...
