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 ...

His concept was to move the obstacle ... An Arduino polls the ultrasonic sensors and provides feedback via the boxes. This completely frees up the user's hands for other tasks. While the prototype has ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair ... field of view of the sweeping sensor, a missile is fired using the dart launcher.

[Eduard] chose the latter, and also included obstacle avoidance sensors in the process. We’ve seen quite a few that use these ultrasonic rangefinders. He decided to go a different route by ...
