I decided to try modifying the ButtonApp sample to use interrupts instead of polling the state of the pushbutton switch.

Gaah, never mind. I just found that the Event Handlers tutorial has been posted in the Projects section.

I'll take a look at that...

Thanks David for the reference to the Make: Electronics book. Exactly what I'm after!! (now to find someone in Australia that sells them!)....

You can also get the eBook version for US $27.99.

You'll probably need three resistors--one for each of the Red, Green, and Blue elements.

1K is probably too high a resistance if you're driving LEDs from the Netduino output pins (3.3v).

Something like 100 ohms is probably more appropriate for Red or Green LEDs. I think Blue LEDs generally have a higher forward voltage, so you may need an even smaller resistor (or maybe no resistor at all). Best bet is to buy a resistor assortment, and save yourself some frustration.

Also, you'll probably want a potentiometer to attach that knob to .

If you're just getting started in electronics, I'd highly recommend the Make: Electronics book. It's a great hands-on introduction to basic electronics. It doesn't cover Arduino/Netduino specifically, but it's a good learning guide.

That is pretty cool. Small and cheap enough to install in a dedicated project . This definitely gives me some ideas. Watch out
