Pure Data to Arduino Over Serial

#include <SoftwareSerial.h>

SoftwareSerial mySerial(0, 1); // Change to whatever you hooked 
                                 // RX, TX up to
	
void setup() {
 mySerial.begin(9600);
}

void loop() {
 for (int i=0; i<255; i++) {
 mySerial.write(i);
 delay(100);
 }
 for (int i=255; i>0; i--) {
 mySerial.write(i);
 delay(100);
 }
}

Then, save this Pure Data patch to a text file, name it SimpleExample.pd, and open it up in Pure Data:

#N canvas 499 140 450 300 10;
#X msg -158 30 devices;
#X floatatom -120 111 5 0 0 0 - - -;
#X msg -94 32 open 2;
#X obj -120 78 comport 2 9600;
#X msg -37 33 close 2;
#X obj -117 177 osc~;
#X obj -116 212 dac~;
#X obj -120 140 * 10;
#X connect 0 0 3 0;
#X connect 1 0 7 0;
#X connect 2 0 3 0;
#X connect 3 0 1 0;
#X connect 4 0 3 0;
#X connect 5 0 6 0;
#X connect 5 0 6 1;
#X connect 7 0 5 0;

A nice feature of Pd is that all the patches are in a simple text format.

To Get this Example Working:

Open Pure Data
Open the "SimpleExample.pd" file in Pure Data
Click on the "devices" message box: This will list any available serial ports in a numbered list.
On my Mac, the usb port connected to the microcontroller was on port 2; (it may be different on your computer)
Find the correct port number and change the "open" message from "open 2" to "open (your port # here)".
- To do that, enter Edit mode under the Edit menu.
- Now you can type directly into the message boxes.
- After you change the "open" message, leave edit mode and do the following:

You should see output of the comport changing, and should hear a rising and falling tone.
