I am also working on the same project. Do you have any of the code available (i.e. NetDuino or Brian's code w/o references to the phidget relay). I am looking to create the sequence files on my PC with Brian's code, but store and execute them on the NetDuino.

Yes I have some code ... It is not pretty because I have been doing a lot of debugging with it, but it is functional and may help you to get an idea. I dont store the sequences on the nutduino but rather I use basically brians code except I sned to serial rather than phidgets. On the other end is an app the runs on the Netduino that takes the serial input and turns on the respective relay.

I have attached my project directory. FYI there is a lot of junk in here but mainly the sequencer app is in the root and the netduino side is in the netduino directory. You are welcome to any of the code here, just remember as I said it may not be pretty

Yes, I think you should be able to power the Netuino from the relay board. Not sure why it would not be working.
Can you draw what you have?

well the thing is I am not trying to power the netduino but rather the netduino is sending the power, but it is not however connecting the ground. I am ataching an image of what I have but for the life of me i dont know how this even works as essentially the netduino is grounding to a completely different system. At any rate if I try to connect the power from the ralay board to power even just the 595 circuit then nothing works.

As I said this does work but I dont know how, or for how long.  diagram.pdf   740.53KB   9 downloads

Hi Thomas, You need to have a ground conection between the Netduino and the breadboard - this is missing on the diagram you posted. Without the ground, the 74HC595 will not be powered corectly. Current from Vcc will be returning via the I/O pins. Paul
