Breadboards can be quick for trying out a simple circuit, but they are really clumsy when it comes to actually USING that circuit.
So step up to the next level of circuit prototyping with a custom shield like this one for the Propeller Platform from Gangster Gadget.
The picture below is a general purpose prototyping board - called a "shield" in modern terms.
It is used to wire to a custom circuit that can be plugged into the host computer.
So we can try out something without hacking the host itself.
This shield offers:
Stereo audio output
A great big LED to blink
A switch connector
and four efternal power connectors.
On the right side of the shield the processor pins and power pins are labeled with a stick-on.
That makes it a lot easier to wire to the right pin.
This shield plugs into the low order connector on the GG Propeller Platform board. (the red board)
Materials needed:
1 each "Perf Board" circuit board with holes on .1" centers and a solder pad per hole big enough for the circuit you want to build.
2 each Wire wrap header - male - 20 pins
Soldering Iron with a fine point
Small diameter solder.
A circuit to build (I'll add that in a while)
software to drive the circuit you added!
First, lets build the bare shield...

Pin spacing for the headers on the GG Prop Platform are standard .1" spacing.
So regular perf board (from Radio Shack even) will work fine.
First step is to trim the perf board to size.
It can be snapped apart by carefully aligning a row of holes along the edge of a table and just snapping the free end down.
Hold the side on the table firmly to the table and it will break cleanly (sort of) along that row.
Clean up the snapped edge by rubbing the edge on sandpaper, just so it is neat and doesn't snag on stuff.
For this Instructable we will make a full shield - it will attach to both headers and sit over the host board.

Couldn't figure out how to do that after it was published.
So my apologies if it caused anybody any problems.
(It was my first time, after all!)
