Piezo elements can do other things, including sensing compression. Often the chunk of crystal is stuck with adhesive to a backplate which can enhance its sound-making potential when the crystal changes shape rapidly. object we take half of the distance travelled. A piezo element is a chunk of piezo crystal with some electrical contacts. The ping travels out and back, so to find the distance of the The speed of sound is 340 m/s or 29 microseconds per centimeter. Long microsecondsToCentimeters(long microseconds) and return, so we divide by 2 to get the distance of the obstacle. This gives the distance travelled by the ping, outbound According to Parallax's datasheet for the PING))), there are Long microsecondsToInches(long microseconds) of the ping to the reception of its echo off of an object.Ĭm = microsecondsToCentimeters(duration) pulse whose duration is the time (in microseconds) from the sending The same pin is used to read the signal from the PING))): a HIGH We give a short LOW pulse beforehand to ensure a clean HIGH pulse. The PING))) is triggered by a HIGH pulse of 2 or more microseconds. play the tone corresponding to the note name This is the code(I think you can ignore the servo and led pins, they are extravaganza stuff) #include But the piezo only makes a 'beep, beep beep' sound continously without making any noticeable melody notes which wasn't a surprise. It is tiny ( 1.2 cm), available in voltage ratings from 3.3V to 12V (5V is most common), and. You can generally find them at any electronics shop at a price range from 20 to 70, i.e.

I just pasted the piezo music code in to the ping sensor code and fortunately it works. Piezoelectric buzzers or simply piezo buzzers are used mainly in alarm circuits to serve as a beeping or security alerting device mechanism. I am currently working on a piezo music element which plays a melody when the ping sensor detects 'nothing' within its vicinity(If an object is within 60 inches, it turns off). Hi, I am a beginner programmer with abysmal knowledge on the correct terminologies of arduino so excuse me for my cheap terms.
