With each contact you make, the red LED lights up ... and B) with only an Arduino UNO, ultrasonic sensor, force-sensitive resistor (or push button), and piezo buzzer. The tone generated depends ...

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 ...

Enclosed are the ultrasonic sensor, a temperature 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 ...

In truth, my intent is not to provide a new translation of some well-worn “Arduino & Ultrasonic Sensor” tutorial ... on an integrated three-digit LED display. Because the module delivers the same data ...

Shifting to the new waterproof ultrasonic sensor is not a big deal, since it’s pretty easy to modify some example codes to use it. The quick road test, oh it’s a simple approach to display the ...

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...
