OK, So my older brother recently got angry with his trusty XBOX controller, and one of the analog sticks had failed within it. This struck an idea and I was pretty sure all an analog stick was, was two variable resistors. (which they are!!!) So with only one working I decided to desolder it out of the board, this was surprisingly really easy :L and then wacked it on a piece of stripboard to test what values they give off etc. It turns out the spectrum you recieve back is 1-100% it is really precise and you can get 0 back or 1023 and when it idles is resets itself and goes back to the middle!
So as my pan and tilt mould came throught the post today I had a little go and it works great, controller a camera with an analog stick is really cool. But I thought of controller the colour of an LED with this analog stick. having a 2D plane means I can set each pixle 1024*1024 to a seperate colour ;D.
So my question is, will mapping this out on the plane be possible to send the colour over to an LED?
Thank you very much, and here is a picture:
Thank you all for your help Trevor Boultwood!
