To make the connection, solder the leads of the resistor to the leads of the piezo element in a parallel fashion like this If you've never soldered before, you might want to check out our Soldering 101 tutorial. However, that might not form a proper connection, so we'll solder them together. We could simply jam the resistor and piezo element leads into the Duemilanove's female headers. Out of the box, our first step is to wire a resistor to the piezo element. In this guide we'll be using an Arduino Uno for the example code, but this kit could be used with any device that can detect a small (less than 5v) voltage in an analog fashion. If this doesn't make sense now, don't worry, it will be explained further later. These are used in parallel with the piezo elements as pull-down resistors to ensure a good read of the voltage produced by the element. The other main component of the kit is the bag of 1M Ohm resistors. Piezo elements come in lots of shapes and sizes, but the ones in your kit are well-suited for detecting a hit or finger press. The piezo element has two leads, and when the pad is pressed, the element generates a small voltage across its leads. The first component is the piezo element itself. We call this the drum kit because we first used it to generate drum sounds using an Arduino and MP3 player shield, but it could be used with any other hardware that requires percussive velocity input.Īlong with everything inside the kit, we will be using these items in this guide:įirst, let's talk about the two main components of the kit. Once you are able to detect voltage levels from the piezo sensors, you can use them to trigger sounds, turn things on and off, start your car, etc. This guide is a simple introduction to working with the piezo elements. In the past I have used these piezo sensors to rig up my desk and couch to play sounds when people interacted with them. The Piezo Drum Kit gives you the sensors to turn virtually anything into a five-piece drum kit.
