Nice job.


I'm wondering how to perform with some precision the following task on two ranges:  (0-100Hz)  and (20k-50kHz)

to set a Fo frequency and amplitude
then output an n number of signal periods accurately (in order to perform a FFT only on that cycles)

I tried to approximate with delays but i still have errors Sad   
What I did was load an app called Signal Generator (There are tons of apps on play store for this) on my phone.
Link the phone to a very basic amp.
And it works like a signal generator for me.
Only problem its limited to about 6 volts.
I need something that can output 0-440 Hz at 220 volts. Still working on that. But this gets the job done for me right now. And it took me like 15 min to hook up.
