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 ...

Thankfully, there's an Arduino project to help you out with that — this gesture-controlled system for VLC. It features two ultrasonic sensors mounted on your computer's display monitor (much ...

The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...

[Mike] lives in a temperate rainforest in Alaska (we figured from his website’s name) and uses a 570 gallon oil tank to supply his furnace. Until now, he had no way of knowing how much oil wa… ...

Watch the demonstration video below to learn more about Zola’s project which uses TX and RX transducers desoldered from an HC-SR04 module, together with a pair of Arduino Uno development boards ...

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

Arduino is able to interpret signals from a variety of sensors. By placing a unit equipped with an ADXL345, an accelerometer ...
