I’ve been wanting to get into using bluetooth with arduino for a while now. I just couldn’t force myself to pay that much for them though. I’m looking at trying around $15 for the arduino and bluetooth module kind of cheap. So, I found this module on deal extreme that’s only $6.60 USD( http://www.dealextreme.com/p/wireless-bluetooth-rs232-ttl-transceiver-module-80711 ). Dang good price for a bluetooth module from what I’ve seen out there. Only semi-issue is it’s slave only, but that’s not too much of a biggie for me.
Anyway, I’ve never worked with arduino and bluetooth before. Is it really as simple as hooking up the tx/rx of the module to the tx/rx of the arduino? That just seems a bit simple. My first little invention I’d like to do is make a simple bluetooth controller for an android device. I am guessing it can be fairly simple as just emulating a keyboard, though I’d like to have support for analog as well. Any ideas on this also? How would I go about getting it to show up as either a keyboard or joystick/gamepad?
Thanks for any help/insight you can give! ( I swear I start way to many projects.)
