    hey I'm working on something small and I got a piece of Glass with a rectangle on it (1cm high x 5cm long) and a square (1cm x 1cm).
    Now what I need is when I Touch the square on the glass, a light bulb should light up at 50% brightness. And when I slide my finger on the rectangle (from right to left) Then the light bulb should Dimm itself and get brighter again if I slide to the right.
    What will I need to get and what type of glass is best for this?
    LOL yea I'm a bit of a noob so any suggestions would be highly appreciated.

    Welcome.
    Buy an iphone and get the iphone software that is already out there and do it.

    Before asking what the software is, try Google.

    Well That really helps me.
    I don't want an app for the iPhone to do this, I want to make an electrical Circuit. This is an image of what I mean by the glass and Touch buttons:

    I hope you understand now!

    Then try to find a capacitive touch screen.
    Making one requires more than a N00b's experience.

    Find one and then you have to learn using programmable chips so you can do what ever you want.

    Are you game?

    Some PICs from Microchip have a capacitive touch module, for example the PIC16F1823.
    I'm not sure what types of glass would work and I haven't used it. It's designed for buttons so the slide might not be possible.
    It's also going to require learning how to program them and a PIC programmer. Not very simple if you are starting from scratch.

    Hello,

    Most "glass" touch switches have a damped metal on the glass surface.
    This metal acts as a "touch plate" that makes it a capacitive sensor.
