Send values to Serial

Hi!

I’m a begginer in Touchdesigner, so I’m having problems to do a simply thing. I want to send data to the serial in order to recive this data with my Arduino.

I have an Audio Analysis program done with Touch Designer, that look like this: (It is done from a Matthew Ragan video from Youtube)

The thing is that I want to send values or something to the serial, in order to activate some leds with Arduino, through some conditions. I know the program is so simply to do, and I read a lot about Send Data to the Serial, but I dont know how to send the values that are shown in the different LOW, MID and HIGH audio bands that I have in my Audio Analysis in order to recieve the reference to this values in Arduino.

I have this code in Arduino to recieve and work with data from the serial:

int incomingByte = 0;   // for incoming serial data

void setup() {
        Serial.begin(9600);     // opens serial port, sets data rate to 9600 bps
}

void loop() {

        // send data only when you receive data:
        if (Serial.available() > 0) {
                // read the incoming byte:
                incomingByte = Serial.read();

                // say what you got:
                Serial.print("I received: ");
                Serial.println(incomingByte, DEC);
        }

        
}

I really need help, I was all the week reading and trying things with other topics in this forum but I couldnt do it. I would need need to know concretly what I have to do.

MILLIONS OF THANKS TO EVERYBODY! :smiley:
