sschocke 1:f07afcffeb5a 47
sschocke 1:f07afcffeb5a 48 The first color in the array will be written to the LED closest to the data input connector.

sschocke 1:f07afcffeb5a 59 Setting this to true changes the behavior of the write function, making it enable interrupts
sschocke 1:f07afcffeb5a 60 after each color is sent, about every 60 microseconds.
sschocke 1:f07afcffeb5a 61 This allows your program to respond to interrupts faster, but makes it possible for an interrupt
