The Dangershield is quite known in Arduino-world I think.

For Netduino, it didn't worked so well. For several reasons:
- Analog ports are connected to +5V
- The buzzer isn't connected to a PWM pin
- The 7-segment isn't connected to the SPI bus

With Arduino, those problems don't actually exist. But those issues make it a very annoying thing for Netduino.
That's why I have it for months now, and never used it. Quite a waste. So I changed that.

I made a small bridge so it's not connected to +5V but to +3.3V instead, like this:

Also, I wrote a bitbang feature for the buzzer and 7-segment display.

Code is available at http://netmftoolbox.codeplex.com/

Hopefully someone else can make this board a bit more useful now ;)


Ps. did I mention it also works for VB2010?

:D
Just so you know, you can use the classes seperately as well, for those components ;)
