It's easy to describe what you can see on the oscilloscope's screen:Probedude wrote:Boy I'm confused as to what could be the problem. You mentioned you have an oscilloscope.
- what does th signal look like coming out of the Atmel when it is hooked up to the 47 ohm resistor to the base of your NPN transistor?
- what is the part number of your NPN transistors?
Thanks,

Nothing!
Not a single peak comes out of the MCU...
When I test the MCU only, without the transitors, the signal l0ooks normally...
The transistors are 2N3904, as listed in the parts list an they're working...
