Re: PMOS in parallel with NMOS

Nothing "bad" happens. Also, the green LED's don't glow yellow.

At this point, I am not as worried about the LEDs as I am the MCU.

I already fried some AVRs like this, driving three colors LEDs without
resistors. They shine very bright, but last very short (days).

I am pretty sure that even a 9 volt battery can blow out a transistor
or LED.

And 5 volt can blow out a uC.
