Is there a way to make this all work using Ken's instructions?
This protoshield looks infinitely easier than the circuit so if I can get away with the easy/lazy approach for now.. would I just need a smaller LED and a smaller resistor?
T12 & 13 etc are transistors... but what kind?
LED 6 - is that the part number underneath it?
R22 & R23...one says 100 and the other "DNP"... not sure what this is?
is there anywhere that explains what this all means?
The voltage on a Mega pin is 5v when high, 0v when low, simple.______Rob

Even when you have an external 9v power supply instead of USB power? And if so, is there any way to get the digital pin to output the full 9v from my power supply, or should I be doing something else?
