stamp connection
connection question
i wrote a sample program on the computer and it seems to be working okay so
now i want to connect LED's to my stamp to see if the program is working the
way i think it is
my friend gave me a carrier board and the stamp so i have just the stamp, the
port for the computer and the battery... nothing else except holes.
i see where the name of the pins is written on the board between the actual
pins and the block sockets with the gold tips extened which are atached to the
board around the chip...
where do i make my connections as far as connecting the led. i see that i
connect the led to the pin and have a vcc applied. are all those holes on the
board that are in the same row as the pin number, do they all correspond to
that pin? do i need to connect anything to the gold tips coming out?
- thanks :-)

I was about to point you to the new Stamp2 Manual, but then when I looked
at page 19 which shows the mechanical layout of the Stamp2 Carrier board, I
see that there is an error. The Stamps are connected to the gold header pin
and the two holes next to the gold pin are associated with the labeled
Stamp pin. Notice that pin 4 and 23 look different, but that is because
they are connected to the ground plane of the board which is connected to Vss.
Your LEDs should be connected to the Stamp I/O pins through current
limiting resistors (330 to 1000 ohms will work in most applications,
depending on your LED).

Looks like I may have jumped the gun a little. The text in the Stamp2
manual adequately describes the layout, even if the picture is incorrect.

LaQuida,
You and I are both learning about the Stamp. Let me suggest
before you start soldering LED's to your carrier board to
experment with. Go to Radio Shack ( RadioShack.Com is better
) and buy a Experimenter Socket Board, also known as
Solderless Protoboards. Try RS#910-1262 or RS#910-1265. This
is one of those item where the board can't be too big.
Digi-Key and Jameco also carry these items.
You will find that the pins on the underside of your carrier
board will fit right into the socket without solder. You can
also plug LED's, resisters, capacitors, ect, ect... into this
board without solider anything. That means easier
construction, and mistakes can be fixed. Plus you can reuse
your resisters and other components, as you just unplug them.
If you start soldering and desoldering your carrier board, it
won't be long before you have a mess.
When you finish your project, you can solider your work to a
Breadboard such as RS 910-3810 or RS 910-1268. BTW, I don't
work for RadioShack, I just happen to have a catalog handy.
Other companies sell the same items.
Have Fun
