Oops!  Typo on my last post. I ment to say      Brian: This is what i am hoping to see eventually!

Trying to see clock signal on an oscilliscope
I guess flipping a pin on and off to make a square wave will work but then won't my 9600 baud "hello world" on pin 3 get messed up... I wanted to see both work at the same time to...

I have a simple ISP boot programmer made out of two Unos.  It lets me load the Arduino boot loader to any 328P-PU chips I buy that do not have the Arduino boot ,loader...

Thank you!  I will keep ity mind for sure once I have a stable wave form to see.

Thank you everyone!  I seem to get a decent sine wave off pin 10 and espcially 9.  15.976 MHz... good enough for me :)  But this is the XTAL not the internal clock...
