Relay''s

Go to http://www.ktmarketing.com/CNC.html and select the 5th link from the
top titled "Parallel Port Hookup to Controller". At the bottom of that page
you will find an explaination and a diagram on how to use a transistor ( a
2N2222 will work fine) to drive a relay. Don't forget to get a diode also or
you will likely pop the transistor. Just replace the term PC and Printer
port with Stamp.
