Basic Stamp 2 Project 3 - Driving a Mechanical 5v SPDT Relay

This is my third project of basic stamp 2. I've been very happy with the basic stamp and i like to share these projects.

Notes:
1 - You NEED to use a driver circuit for mechanical relays. I've made the diagram:

And a simpler one for beginners:

Also the pin orientation for the 2N2222A Transistor:

2 - You may need to turn the volume up to hear it clicking. That's proof it's working.

Code (Maybe it's realy simple, and assuming you connected the
base to pin 1 through the 1k or 2.2k ohm resistor ) :

' {$STAMP BS2}
' {$PBASIC 2.5}

DO

HIGH 1
PAUSE 500
LOW 1
PAUSE 500

LOOP

Thanks for watching!!!!
