This is an introduction on how to setup, make a basic connection, and send data to and from an Arduino using Bluetooth!

Bluetooth is great for transmitting data over medium distances and what's more, Arduino just treats it like a serial data connection. This means that we can use the Serial Library. That's a nice thing to have.

But what to pair the bluetooth to? And how do we do that? This covers all that. What you use the new found connective abilities for is up to you.

Here are some ideas though:

Wireless programming.
Wireless switches.
Wireless custom remotes.
Pairing with Android for some real power behind it.
Simple alarm system (someone is at the door or in room X)

As always, I made this at TechShop


Step 1: Materials

Since this is just connectivity, there are very few parts

1. Arduino Uno $40

2. Arduino Shield $10

3. Bluetooth Modem $40-60
Here's the one I'm using from sparkfun

Overall, you created a good 'ible'. <br> <br>I understand that you bought the Bluetooth modem from Sparkfun to go with their prototype shield (I also have one) but I agree with '3tuxedo', $15 is a more reasonable figure for a Bluetooth modem. <br> <br>&quot;If you are using Windows, I might recommend HyperTerminal&quot; <br>What? Don't do it. There are lots of great terminal emulator programs out there like X-CTU and TeraTerm. <br>
im sorry but 40 - 60 $ for a bluetooth receiver is ridiculous. I just bought one on ebay for 8 bucks my friend!
