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 ...

allowing the sensor to measure the distance and subsequently prompt the buzzer to emit the right note. Since the project uses pretty basic components, the Arduino code is equally basic ...

[Andy] demonstrates building an ultrasonic anemometer using a cheap after-market parking distance sensor kit and an Arduino. Demo video after the break. Aside from the price, these kits have the ...
