Build Your Own Ultrasonic Sensor To Measure Distances With Arduino

The ultrasonic sensor with Arduino allows us to measure distances through ultrasound. It is very common to find this type of sensor in today's cars. The objective is to show how we can build real systems with this prototyping board. I will elaborate on the connection between the components and the code necessary to make it work. How the Arduino ultrasonic sensor actually works To measure distances with Arduino we can do it in different ways. There is the infrared sensor, which uses the properties of light to calculate distance, and the Arduino ultrasonic sensor uses the properties of sound propagation to measure distances. More specifically uses ultrasound. These types of sound waves are above the spectrum audible to humans. The operation is very simple. The sensor sends an ultrasonic wave through the trigger, bounces off the object, and the receiver or echo detects the wave. Knowing how long this wave has taken to travel, we can know the distance. You only need to use
