I'm trying to do blink over i2c per this page: http://jason.pepas.com/wiki/index.php?title=BlinkMeetsI2C
I've wired everything up, and got my two Arduinos powered up but my slave i2c Arduino never blinks. I have my Arduinos hooked up like this but it's still not working. Did I wire something up wrong? Basically pins 4 and 5 on each are tied together with a pull up resistor. Pretty simple I'd think.
