Hello!

I got two Arduino Unos and i want to send data between them via bluetooth.

I've never used bluetooth before so i have no idea what to buy.

I would like the modules to have pins so i can stick them to a protoboard.

So.. question is.. can anyone link (from ebay) two Bluetooths that can communicate with each other and that cost around 1-20 dollars apiece?

Thanks in advance!

Search eBay for: Wireless Serial 4 Pin Bluetooth RF Transceiver Module

Currently the lowest price is $7.78 with free shipping. Don't forget to get two.

The modules act as a serial cable so use Serial or the SoftwareSerial library.
