EEG Signal Generator

I have an EEG signal generator project (want create sine, square and biological waves) should i use arduino to save waveforms? how can I lower the amplitude to microvolts?
I'm not sure where to start, any ideas on how I can do this.
Thanks in advance for any guidance.

I've found what appears to be complete documentation of Jesper's project.

The design includes a 256 byte wavetable. You merely plug in the 256 values to be repeated in each cycle and the chip plays that back over and over. You can set the repetition frequency in firmware and do away with the RS-232 control.

Also, here is another if you prefer German.

Here is a project that generates a sine wave by reading it from a table of values, it is interrupt driven and written in Gnu C, so it might be easier to understand.
