Hi angelman,

I think those posts can help you figure it out:

Multiple Values from Processing to Arduino through Serial Port

I have managed to send one value from processing to arduino. (which maps mouseX and lights the respective LED on an LED strip of Neopixels) I went through a lot of forums and tried to send Mouse Position(2 values ) from processing to arduino … By trying to separate the numbers using substring and toInt … But then the program doesn’t seem to be working. can anyone share an simple example that sends and receives X and Y values, or multiple values.

Send 3 variable to Arduino?

Hi, I’m trying to send 3 variable w1, w2 and phiV which are 3 parameter changing with the mouse tracking. I was trying to place those variable in 3 arrays and add it in a string but it didn’t work. I think there is one or several steps i have missed somewhere. Can I send a float array or just an int array? I put my program import processing.serial.*; Serial arduinoport; float w1, w2; float w12twist = 10.0; //int x=1; int Um=100; int Vm=100; float phiU=0; float phiV=HALF_PI/2; float X1t,…
