ATtiny85 and Adafruit NeoPixel

If you decide to program an ATtiny85 to control Adafruit NeoPixel, it may be necessary to reset chip fuse to 8 Mhz.
I bought ATtiny85-20PU  from mouser.com. This chip has an internal clock and can do 1 Mhz and 8 Mhz.
I believed it is shipped set to 1 Mhz, which will not work with the Adafruit NeoPixel.

Here are a few reminders.

• Download Arduino 1.6 or greater

• Installing the ATiny85 configurations in the Arduino IDE

• Click File -> Preferences and enter the following url in field Additional Boards Manager Urls

• https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-manager/package_damellis_attiny_index.json

• Click Ok
• Follow this tutorial to install the ATtiny configurations: Programming an ATtiny w/ Arduino 1.6 (or 1.0) 

• I am using an Arduino Uno to program the ATtiny85, configured as follow

• If you are using a programmer to upload the code to the ATitny85, you still need to reset the fuse once.

• Load the sketch -> Examples -> ArduinoISP
• Compile
• Upload into the Arduino Uno

• Load the Exemples -> 01.Basics -> Blimk
• In the menu tool select
• Board: ATtiny
• Processor: Attiny85
• Clock: 8 Mhz (Internal) 
• Port: Com port used by the Arduino
• Programmer: Arduino As ISP

• Fuses
• This is the tricky part. It is necessary to reset the clock of the chip.
  It is a one time operation.
  From the menu Tool, click Burn Bootloader

• Now you can upload the code from NeoPixel Code from Adafruit.It should work.
