Helllo, i'm really new to the basic stamp world.. i'm trying to interface my homework board to my halloween prop control board to trigger the relays on it.. it has 8 12v dc relays and wel my question is this.. has anyone done anything similar to this and ifso what did you have to do to get it to work right with out buring up the homework board??


thanks in advance,

rob

People do that all the time -- a good friend of mine runs a Halloween prop builders' forum called www.methodzofmadness.com.

The key for running 12v relays is to use a ULN2803 as the interface; you can't connect the BASIC Stamp directly. Download StampWorks from our web site to get the skinny on the ULN2803.

Yes, the StampWorks manual is on the Parallax CD under "Documentation".· You will not be able to retrieve your code from the BASIC Stamp.· The only option is that you can purchase EEPROM burner (some what expensive) and copy your code to other EEPROMs.· However, you will not be able to see or alter your code.·

Yes, "Save early, save often." -- cliche worth living by when it comes to computers.
