| 説明 | The installation detects where people are and how close they are using sonar. Like bats, these little black cylinders fire off a pulse of super high frequency sound and then time how long it takes to get the echo.The closer people are, the faster the motors vibrate. The computer program running on the arduino detects if people are still, and then stops the vibrations and changes the slide.They plug right into the arduino shield and I can read the distance out in centimeters! The sensors came from www.robot-electronics.co.uk/ |
