Digital volume control

Project ideas.

Ideas

  • Stereo digital potentiometer
  • MSP430 microcontroller
  • Incremental rotary encoder
  • (optional) LED bar graph
    • shows percentage of the volume when the levels are changed
    • VU meter when not changing volume
  • (optional) USB control (launchpad)
    • can send the VU values to the computer
  • (optional) IR control?
  • two switches or button wheel (rotary encoder?)
