[Logic][Gates] Implement 5 button MP3 player interface using CEDER

Develop and submit an original logic circuit for the user interface of a 5-button MP3 player. The interface must display the volume as an 8-LED bar graph, the track number and Play/Pause indicators (one LED for each). The MP3 player interface must have the following controls and displays: 1. A PLAY/PAUSE button. 2. VOL+ and VOL- buttons 3. <- (prev) and -> (next) buttons 4. An 8-LED bar graph indicating 8 volume settings 5. A 2-digit decimal display -two 7-segment displays (available in the input/output palette in CEDAR) to indicate the track number. 6. One LED which indicates PLAY mode (on) and PAUSE mode (flashing 1Hz) OR Two LEDs - one for each mode. There is no requirement to implement the MP3 playing function, the A-D convertor, audio amplifier or other functions. I will share the rest of the detail with short listed candidates.
