Electronic Organ

Not open for further replies.

I am a Digital Systems III student and hav e been assigned to do a project on an Electronic Organ,

This project will enable the user to use the keypad to play one of sixteen audio tones.It must feature the ability for the user to record a minimum of ten tones together with the duration of the keypress, so that the exact tune can be played back. Tones will be created by setting the internal timer in a specific way and outputting a certain frequency on a port pin.This must be connected to a circuit that can drive a loudspesker directly.

Please help me with whatever information /data/refernces that can assist me with this project. How to go about it and any other information that can be of help ASAP.

Thanking you in advance.
