Recently, I found a very magical device in my desk drawer. Upon closer inspection, it turned out to be an ultrasonic distance sensor from a kit given during a Maker Education Instructor training in Zhengzhou back in 2016. This device has been lying in the drawer for nearly 5 years. Is it still usable? I … Read more

The ultrasonic sonar is a device that measures the distance to an object by emitting sound waves at a frequency above the human hearing threshold (typically above 20KHz). Its working principle involves sending out sound waves and measuring the time it takes for the sound waves to bounce back after hitting an object. By calculating … Read more

Hello everyone, this is the second lesson, where we will add an ultrasonic sensor to the previous programming car. The main function of the ultrasonic sensor is to measure distance, and using this feature, we can create very useful things. We’ll talk about the projects later; first, let’s get familiar with the sensor. Ultrasonic Sensor … Read more
This robot car is very simple. It uses ultrasonic sensors to measure the distance in front and the Arduino controls the car to move forward, backward, or turn left and right based on the received distance. In other words, it has its own way of “thinking” and can wander around a room without bumping into … Read more
The Minor Snow solar term signifies the gradual onset of colder weather, and the season of falling snowflakes is approaching. During this time, designing a sensor capable of detecting snowflakes is particularly interesting and practical. This article will boldly envision three theoretical design schemes to help everyone better understand and apply this technology. The first … Read more
