 ==== Step 1. Plug in and Install driver  ====
 We'll start out easy, by plugging in the atmega32u4 board and installing the driver. For mac and linux users, you can skip this step! If you're using windows, however, you'll need to do this:
-{{:tutorials:make:ledbelt:leonardoinf.zip|Download the INF driver by right-click saving this file and saving it to the Desktop}} then uncompress the folder
+[[http://www.adafruit.com/datasheets/atmega32u4cdc.inf|Download the **inf** by right-click saving this file and saving it to the Desktop]]
 Then plug a mini-B cable into the board and you should see the LED light up on it and you'll be asked to install the driver.

+We'll have to install a version of the Arduino IDE called Teensyduino and our LED strip library, so we can program the controller chip.
-We'll have to install the Arduino IDE and modify it so that we can use it with this chip.[[http://ladyada.net/products/atmega32u4breakout/#using_teensyduino| To do this, please visit our detailed instruction page on installing teensyduino and modifying it so it works with the 32u4 board.]]

-This is the most basic demonstration code of using HL1606-based digital LED strips.
-The HL1606 chips are not very 'smart' and do not have built in PWM control. (Although
-there is a fading ability, its not that useful)

-If you've already uploaded something to the board, you might have to press the reset button to enter the bootloader (the green led will be pulsing), then check the Serial Port menu again to see the serial port appear.
-To upload, press the reset button, you will see the green LED 'pulse' in and out like its breathing. As soon as you see this happening, press the **Upload** button in the IDE
-If uploading goes well, you should see the following:

-If you see something like **"buffered memory access not supported. Maybe it isn't a butterfly/AVR109 but a AVR910 device?"** That means you did not upload during the bootloader time (10 seconds or so). Press the Boot/Reset button on the atmega32u4 and try again!

 That's it! Now the project is done. You can keep the battery pack and microcontroller board in your pocket and wrap the belt around you
