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 ...

All of these projects either use minimal components ... and B) with only an Arduino UNO, ultrasonic sensor, force-sensitive resistor (or push button), and piezo buzzer. The tone generated depends ...

Enclosed are the ultrasonic ... sensor and an LED indicating the power status. On the other side of the CAT5 cable can be found an Arduino compatible board with an XBee shield and a 9V battery ...

With materials being simple cardboard, aluminum foil, popsicle sticks, some mesh, and a single ultrasonic sensor for harvesting the transmitter and receiver out of, this is the kind of project you ...
