It's an Arduino Christmas!

It's that time of the year again... and the workshop was bereft of Christmas decorations...

So something was quickly conjured up.

My colleagues, Laura and William, fashioned a cardboard christmas tree. Ryan wired up 6 LED's and some current limiting resistors up to the 6 "Analog in" ports on an Arduino board, and I wrote the world's shortest sketch...

void setup() {

DDRC = 0B00111111;

}

void loop() {

PORTC = int(random(63));

delay (10);

}

How's that?

Minimalist!
