Help with serial object
Apr 17 2013 | 5:30 pm
Hey everybody im currently doing a university project and I have to find a way how to control a LED chain from Max Msp via Arduino.
I want to send a list with 4 values from max to arduino over the serial object. The first value which will choose a specific LED and then the three other values sets the colour.
LED Nr R G B
10 0 0 255
My question is "how exactly do I pack together 4 values and send them through the serial object". I have tried a few solutions but it does not seem to work. Can I send four values into (pack 0. 0. 0. 0.) and then connect it to the serial object.. is it that easy? or do I have to use (atoi) to convert the values into ASCII before sending them to (serial a 9600).
I have never used the serial object before so im not sure how to do it!!
hope you can help :)
