I came across these Force Sensitive Resistors
. I like them a lot and I wanted to do something with them, may be making them more usesable than standing on the breadboard.
Few months ago, I created the pocket-sized RevIO - Arduino Compatible
and having fun with it since then.
While playing with these two, I decided to put them together!
To complicate things further, I wanted to use them wirelessly. So I added XBee module to send commands wirelessly from RevIO to play different drum sound snippets on the PC speakers.
Above was not the only reason to make me put these four force sensitive resistors onto the RevIO case permanently. I saw that I could used these force sensitive resistors as the controllers, such as robot controller, or radio control car, or anything that required the maximum of four controllers.
This instructable only shows how to use these FSRs to make drum sounds as they are pressed.
Here is the video when I tested them.
