* Input:
* ledarray: An array of GRB data describing the LED colors
* number_of_leds: The number of LEDs to write
* pinmask (optional): Bitmask describing the output bin. e.g. _BV(PB0)
*
* The functions will perform the following actions:
* - Set the data-out pin as output
* - Send out the LED data
* - Wait 50<EFBFBD>s to reset the LEDs
