Sadly, I can only talk about stuff that didn't work out this week...
I was trying to connect my Arduino to Max, to send data from Max to LEDs that are connected to the Arduino, to control the LEDs one by one.
I don't know yet where the problem is, but the Arduino and my Mac are not interacting correctly with each other. I tried some other tutorials on the internet, set up the Arduino and Max as it was supposed to, but in the end non data was transmitted into Max or back... I guess it's a "serial" problem., I'll work it out and come back here once it is done
Here are at least some picture from my desk...
