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 ...

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 ...

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 ...

After a while, you noticed your skills started increasing, and your comfort level with different projects improved ... [Greg06] even included an ultrasonic distance sensor for the obstacle ...
