Small Enclosed Piezo Elements w/Wires for Raspberry Pi
This small enclosed piezo elements w/wires can be used as speaker/sounder for making beeps, tones and alerts AND when glued to a surface. It can commonly used as percussive sensors in musical instruments, drum pads, kits, etc.It also can be used to detect fast movements like knocks. You can use it under a drum pad to make a drum/crash sensor.
This small piezo element is nicely enclosed so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. It's rated for up to 9Vpp use but you can also use 3V square waves and its plenty loud. For music use with an Arduino, check out the Tone tutorial. For sensing, the Knock tutorial is your guide! There are thin wires attached, we plugged them into a solderless breadboard, but they might too thin to plug in directly into the Arduino socket headers.
Thanks for your attention,hoping you will have a nice shopping!
