This Arduino project controls a servo motor based on distance measured by an HC-SR04 ultrasonic sensor, adjusting to four angles for different proximity ranges. It updates only when significant ...

This project involves an Arduino-based system that measures distance and monitors temperature and humidity. The system uses an ultrasonic sensor for distance measurement, a DHT22 sensor for ...

Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...
