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 ...

Inside [Klaus]’ device is an Arduino Uno, an HC-SR04 ultrasonic distance sensor, and an Adafruit Wave Shield. Originally, this parking/distance sensor used a small TFT to display the distance to ...

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 ...

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 ...

Runner and Arduino enthusiast Nikodem ... a couple of buttons to adjust the distance from 50m to 1,000m depending on your race criteria. All code for the project has been kindly published to ...

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