AD9850 module and Arduino

[Andre Kesteloot]

Alex,
Kudos.

How about writing a short article for the AMRAD Newsletter, based on your e-mail, and add a schematic ?

If you can supply the schematic "on the back of an envelope" we can easily turn it into a schematic suitable for the Newsletter 

Thanks and73

Of course I have a laptop on a small table that I use when I watch TV, so I Googled "Arduino AD9850".  I think I used the second site that popped up.  I had ordered some small breadboards and ready made jumper cables when I bought the Arduino so all I needed was the pin outs, which were on the site.   It took me about 20 minutes watching TV and sticking in the Jumper pins including the 5 volt power from the Arduino, which comes from the USB cord attached to the laptop. It took another 10 minutes to down load the sketch, figure out where to put it on the hard drive, start the Arduino software, load the sketch and up load it to the Uno.  I then hit pause so I wouldn't miss any of my program on the TV and went and found my SWL rig, plugged it in and sat back down and hit play on the TV.

I hacked the sketch by changing the frequency, retuning the SWL rig and there was the signal, right where it was supposed to be.  These things work out of the box and all the info you need is right at hand.  I am impressed and encouraged, they actually work!
