This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

I will use this sensor (or its latest version) in a more complex project in the next part of this post. Stay tuned for that do it yourself project. Below is the Arduino Sketch used to test the ...

In the real world, missile systems use advanced radars ... To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates ...
