This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module ... and best understood by referring the wiring diagram. If everything goes right,you should ...

When you think of Arduino projects ... on how far your hand is from the ultrasonic sensor when you activate it with the force-sensitive resistor. The closest distance corresponds to C, the ...

They rebuild one of the most iconic components for an electronics tinkering beginner ... ultrasonic distance sensor, and what’s fun is, it stays fully functional after the rebuild! This project ...

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 ...

While early scientists and inventors famously underestimated the value of radar, through the lens of history we can see how useful it became. Even though radar uses electromagnetic waves to detect ...
