Hello,
  I'm wanting to reuse a usb erupter to make it into a LED flasher.

  I've figured out how to use arduino uno and get code into the at tiny chip but it only turns the LED off.

  Is the LED connected right to the ATMEL chip and what pin?   I use pin 8 in code and it makes the LED go off but it won't blink.

Does the LED get turned on by the BE chip?

Maybe I have to use a real AVR programmer and just C instead of the arduino method?   I thought it would be cool necklace.

Good day.
