This is the second version of the AVR signal generator. This time it uses a single sided PCB to simplify the project, and has both offset and amplitude controls. All the source code and schematics are available on the website. Signal generators can be very expensive, this version shouldn’t break the bank. – Link

DDS (Direct Digital Synthesis)
ucHobby also has built one of these in another form. It uses a computer controlled interface to the Arduino and the Sig Gen module sits right on top of it.
