It looks to me like its "tinkerkit" connector/s could be used for what you propose.
At the RadioShack clearance yesterday afternoon, I saw a couple of Esploras hanging on the pegboard.
When I got home, I thought, "Darn, I probably should have grabbed one of those."
(Maybe they still have one.)
They did - $13 out the door (80% Off)
"I've done an extensive search on Google and I haven't found much. Any information would be appreciated."
Your idea of extensive is different from mine.
My very casual inquiry found this, at or near the top --
Oh, I found a lot of stuff using Tinkerkit components, but I was wondering if there was a way without having to purchase anything new. Sorry for not clarifying.
"Tinkerkit components" vs. "anything new."
I don't know what "tinkerkit" is, but you'll need other components (if "anything new" means: something or anything not included in the Esplora's box) - namely that LED you mentioned AND a resistor (let's say 470 ohms), and some wires/jumpers to go between those "tinkerkit" headers and that breadboard (saw those at RadioShack, too.)
