Hello,

Is it possible to build an Arduino based function generator? I want to produce a 0,7Vpp (min) to 1,5Vpp (max) sinusoidal signal using low cost equipment...

Thank you

Here is a thread that covers the subject pretty well. Can arduino uno generate sine wave ?

What a frustrating read that thread is. Some nice code/explanation in there though.

You could also look at non Arduino routes using an op
Amp - very cheap !!
Google it

Unless you really need to use an Arduino, there are function generator chips. Something like the XR2206.
