Introduction The goal of this project was to create device similar to a DJ mixing board. Features: Controlling the input and output buffers Applying sound effects Cross fade between inputs

Implementation Starts in Off mode Pressing PF8 Once will activate Normal mode and turn on LED4. Twice will activate DJ mode and LED4 will blink. Thrice will activate Off Mode.

Implementation Normal Mode Pressing PF9 Once will switch all outputs to input0 and LED 5 is turned on to indicate that input0 is being heard. Twice will switce all outputs to input1 and LED 6 is turned on to indicate that input1 is being heard. LED 5 is turned off. Thrice will results in going back to both inputs being heard and LEDs 5 & 6 turning off.

Implementation Normal Mode Pressing PF10 Once will cycle the speakers in a clockwise order. LED 7 is turned on to indicate the clockwise cycle. Twice will cycles the speaker sin the reverse order. LED 8 is turned on to indicate the anti-clockwise cycle. Thrice will turns LEDs 7 & 8 off and stops the cycling of the speakers.

Implementation DJ Mode Pressing PF9 Once will activate a continuous auto cross-fade. LED 5 is turned on to indicate that input0 is being heard. LED 6 is turned on to indicate that input1 is being heard and when both LED 5 & 6 are on it indicates that both inputs are being heard. Twice will deactivate the continuous auto cross-fade and turns off LEDs 5 & 6

Implementation DJ Mode Pressing PF10 Once will Both LEDs 7 & 8 on indicates the Flanger sound effect. Twice will Both LEDs 7 & 8 off indicates the Echo sound effect. Thrice will LED 7 on indicates a Low Pass Filter sound effect. A Fourth time will LED 8 on indicates a High Pass Filter sound effect.

Results and Conclusion Flanger effect Could use more “swooshing”. Other effects cam out well. Auto Cross-fade works really well. Sound effects can applied while in that mode. Speaker Cycling A slower timer would make the cycling more obvious

Results and Conclusion Designing with only 4 buttons and 6 LEDs is difficult. Had be careful designing the interface. Limits how much functionality that can be implemented. More effects could be added. More LEDs would allow visual appeal with light movement.
