Hi There,
Forgive the noobish questions, I have done only a few arduino projects.
I'm interested in using Bluetooth to send basic commands to an arduino uno from a macintosh, using firmata on the arduino. (the arduino need not send anything back).
In researching all the BT options, I'm having trouble differentiating something like the Bluetooth mate silver Bluetooth Mate Silver - WRL-10393 - SparkFun Electronics
with something like this http://imall.iteadstudio.com/im120417006.html.
And for that matter, why not just the basic RN-42 module?
Bluetooth SMD Module - RN-42 - WRL-10253 - SparkFun Electronics
I realize that the Mate Silver is designed for use with the LilyPad and Pro boards, but I see that many people have used it with the uno as well. why is the silver so much more expensive?
Any insight would be greatly appreciated.
Thanks in advance!!
