1 | Get a LilyPad Arduino, FTDI board, and USB cable.

Scroll down to the middle of this page, where there is a table listing drivers for different computers. Click on the most recent driver that is compatible with your computer. If your computer is running OS 10.5 or higher you should use the x64 (64-bit) drivers. If you're running OS 10.4 you should use the x32 (32-bit) drivers. Otherwise, you should use the PPC (PowerPC) drivers. To determine which OS your computer has, click on the apple icon in the upper right hand corner of your screen and click on "About This Mac" menu item.

Now, simply click the "Upload" button in the environment. Wait a few seconds - you should see the RX and TX leds on the FTDI board flashing. If the upload is successful, the message "Done uploading." will appear in the status bar.

A few seconds after the upload finishes, you should see the pin 13 LED on the board start to blink (in green). If it does, congratulations! You've gotten your LilyPad Arduino up-and-running.

If you have problems, see the troubleshooting suggestions.

For more detailed installation instructions, see the guides on the FTDI website

Attach the FTDI board to your LilyPad Arduino board. Attach one end of the USB cable to your FTDI board and the other end to a USB port on your computer.

Browse to your Applications folder and double-click the Arduino application to open the software. (Note: if the Arduino software loads in the wrong language, you can change it in the preferences dialog. See the environment page for details.)

You'll need to select the entry in the Tools > Board menu that corresponds to your LilyPad Arduino. If your board was purchased in 2012 or later, you should select "LilyPad Arduino w/ ATmega328 from this menu".

Select the correct serial port from the Tools > Serial Port menu. This tells the Arduino software which USB port your LilyPad Arduino is attached to. On the Mac, this should be something with /dev/tty.usbserial in its name.

In this tutorial, we assume you're using a LilyPad Arduino Main Board, Simple Board, or SimpleSnap. This tutorial will also work for the LilyPad Arduino Protosnap boards: the ProtoSnap LilyPad Development Board and the Protosnap LilyPad Simple Board. If you have a LilyPad Arduino USB, read the corresponding page in the getting started guide for setup instructions.

Sewing the LilyPad Arduino

See the LilyPad Arduino tutorial on Leah's website for more information about building a working wearable. See SparkFun for more stitchable modules that you can use with your LilyPad Arduino.

To program the LilyPad Arduino, you need to connect it to your computer. The SparkFun FTDI Basic Breakout plugs into the 6-pin male header on the newest version of the LilyPad. Use a USB MiniB cable to connect the FTDI basic breakout to your computer. You can also use an FTDI USB-TTL Serial cable.

To connect earlier versions of the board or for information on other connection options see the LilyPad Arduino tutorial on Leah's website

The LilyPad Arduino is more fragile and easy to break than a regular Arduino board. Don't connect more than 5.5 volts to the + tab or reverse the power and ground pins of your power supply, or you will very likely kill the ATmega on the LilyPad Arduino. You can't remove the ATmega, so if you kill it, you need a new LilyPad.

The best way to attach your LilyPad is to use the current compatible SparkFun connector. To connect earlier versions of the board or for information on other connection options see Leah's LilyPad site.

You have a few options for connecting the board to your computer: the SparkFun FTDI Basic Breakout, an FTDI USB-TTL Serial cable, the SparkFun LilyPad USB Link, the Mini USB Adapter, a regular Arduino board, or your own power supply and USB/Serial adapter.

The SparkFun FTDI Basic Breakout plugs into the 6-pin male header on the newest version of the LilyPad. Use a USB MiniB cable to connect the FTDI basic breakout to your computer. You can also use an FTDI USB-TTL Serial cable.

If you have an LilyPad without pre-mounted pins, solder a right angle male header to the -, tx, rx, 5v labeled holes at the top of your LilyPad to make the connection. The LilyPad USB Link is available here and right angle male headers are available here.

Use the SparkFun LilyPad USB Link

Now you can attach the LilyPad to your computer by plugging the Mini USB into your computer and clipping the alligator clips to the TX, RX, +, and - tabs on the LilyPad. If you have a LilyPad whose TX and RX tabs are underneath a male header, you can trim the header pins to make room for your clips. You might want to cut a piece of foam or felt to put under your LilyPad before attaching the clips. This will make them less prone to slipping. Here is a photo showing the LilyPad Arduino connected to the Mini USB adapter.
