Bluetooth Rotary Phone

Things I bought to make my Bluetooth Rotary Phone. I am blogging about my experience at Google+.

Additional purchases from other sites:

Speaker and Amplifier from AdaFruit: Speaker - 3" Diameter - 4 Ohm 3 Watt and Stereo 2.8W Class D Audio Amplifier - TS2012


You may go with 1 USB cable, I just added two just in-case I needed to charge as well as hook up to the FTDI board.

It might be a good idea to get a USB power brick, I have one from my old cell phone.

Gone with 2 packs of 10 jumper wires. I know I will be likely stripping one end of at least 4 wires to allow more than one cable to the power supply (we need both gnd/vcc to connect to both the arduino and the bluetooth board... Maybe eventually the high voltage board for the bells if I ever find out how to do that.

A few of these items you may be able to get cheaper elsewhere. I recommend looking and if you find something cheaper, why not go for it? An example is the Jumper Wires, sorry sparkfun, I bought these which is cheaper than 20 jumper wires here. I get 120 and mixed.

You only need the 100 ohm resistor, but buying a kit of resistors is useful.
