Interfacing a Qprox SMD (SSOP14) touch slider IC and a MAX7221 with 16 leds (LED bar/VU meter). Everything is connected to an Arduino Diecimila. The code is still raw and extremely basic, features such as buffering/smoothing and host communication are not implemented yet.

  • Hi, very interesting.. so what Qprox you use ? the name of the chips ?

  • What do you think a Ipod is. It's exactly the same thing only in a circle, and instead of Led's changing it moves a cursor on your ipod.

  • No offense, I found it very cool, but how can this be applicated in real life? I mean, how is it useful?

    Could someone please explain! THX!

  • Excellent work.

  • Nice!
