I’m not talking about these: Who doesn’t have hundreds of acres in the game? Roll up your sleeves and get to work, but it’s never enough, it can never be enough. However, in real … 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
This article briefly discusses how to use Arduino in conjunction with an ultrasonic module to create a smart trash can experiment. When a person approaches the trash can, it automatically opens. Trash Can Materials Needed Arduino Ultrasonic Sensor Servo Wiring Connection Wiring Connection Physical Wiring Code #include <Servo.h> const int trigPin = 9; // Trigger … Read more
Introduction to Ultrasonic Radar: The functionality of Arduino is truly powerful, allowing for the creation of interesting projects using various sensors. Today, we will develop an ultrasonic radar using the Arduino board and ultrasonic sensor, capable of detecting distances up to 40CM. When there are obstacles, the scanning interface will display red and show the … Read more
