Hi guys,
I am an Arduino beginner i have a problem in creating a 12.5 Mhz signal.
Can anyone help me out, how to do it.
What seems to be the problem?
as i am beginner i dont know how to start it
Analog Devices make a range of DDS signal generators which are easy to interface (typically three wires for SPI) even to AVR Arduinos.
The AD 9850 is a bit long in the tooth, but still available, I believe.
Look for a ready-built module

There is an example here. It may help you get started

The usual 16MHz AVR based Arduino cannot generate a 12.5MHz signal...
unless the resonator is exchanged from 16 to 12.5 MHz. But even then the signal can not be modulated. What's the use of that signal?
Thank you for the information provided.
i'll try this out
