Making Sounds with an Arduino (including via Max).

To cover: 


Using a piezo disc to make sounds
Give the sounds a duration
Use the Arduino Board with Max

Use a Piezo to Make Sounds

First, use a Piezo to make sounds via the Arduino, (piezos can be used to create sounds as well as 'receive' them, as in the knock example we've covered. 


/* Play notes over serial
 * 
 * Arduino Code Example - playing sounds
 * Example 1: just playing sounds
 * The following program is an example that will play notes 
 * out of the characters received over the serial port. 
 * To try it out, upload this file to Arduino, hook up a piezo 
 * or a speaked to digital pin 8 (black to ground) and send characters to play 
 * each note.
 * Do this by opening the Serial Monitor (button in bar above), 
 * typing a letter in the field that appears below and clicking 
 * on the 'Send' button.
 * 
 * 
 * ----------------------
 * 
 * note - half period (uS)
 * ----------------------- 
 * c    -   1,911
 * d    -   1,703
 * e    -   1,517
 * f    -   1,432
 * g    -   1,276
 * a    -   1,136
 * b    -   1,012
 * C    -   956

int val2 = 0;     // stores the data that came from the port
int piezoPin = 8; // pin number where to hook the speaker
int pulso = 0;    // value of half pulse

void setup() {
  Serial.begin(9600);
  pinMode(piezoPin, OUTPUT);
}

void loop() {

    val2 = Serial.read();
    if (val2 == 'c') {

Notes with duration:


/* Play notes over serial v0002
 * Example 2: upgrading to notes
 * Notes have duration in time, this program will play a tone for some time, 
 * and then go silent, instead of keeping it sounding forever, 
 * as the previous program does.
 * This example also plays strings of letters.
 *
 * Send the Arduino letters by opening the Serial Monitor (button in bar above), 
 * typing a letter in the field that appears below and clicking 
 * on the 'Send' button.
 * ----------------------------

 * note - half period (uS)

 * g    -   1,276
 * a    -   1,136
 * b    -   1,012
 * C    -   956
 *
 * We create a function that will take care of
 * playing a tone for a while and go silent
 * afterwards

#P comment 36 491 636 196618 - Patch adapted from Thomas Ouellet Fredericks' "Simple Message Sytem" example. Serial writes are possible \, but not implemented here: see the S.M.S. code.;
#P comment 35 433 643 196618 - You may have to change your serial port to suit the port in use. Click on the yellow button to see the guts of the serial read and to make changes to how the patch talks to the serial port.;

#P comment 97 175 125 196617 At minimum \, you need the "arduinoreader" patcher at the right \, which does the work of reading the pins. The toggle turns serial reads from the Arduino on and off.;
#P comment 495 179 111 196617 The right-hand yellow button opens the patch so that you can adjust settings \, like how often to read from the Arduino and which port to use.;

Arduino Patch


  /*  
 *  Arduino2Max
 *  Send pin values from Arduino to MAX/MSP
 *  
 *  Arduino2Max.pde
 *  ------------  
 *  Latest update: September 2007
 *  ------------
 *  Copyleft: use as you like
 *  by djmatic 
 *  Based on a sketch and patch by Thomas Ouellet Fredericks  tof.danslchamp.org
 *  
 * 
 * 
 * Don't worry about the LED (which you can connect to digital 13 if you want) as it doesn't contribute anything new.
 * Attach a potentiometer to 5v and Ground (two outer connections), and the sensor (central connection) to Analogue in 5.
 * 
 * In fact, the code below reads ALL the analogue pins, so you can use any...

int x = 0;                              // a place to hold pin values
int ledpin = 13;

void setup()
{
  Serial.begin(115200);               // 115200 is the default Arduino Bluetooth speed
  digitalWrite(13,HIGH);              ///startup blink
  delay(600);
  digitalWrite(13,LOW);
  pinMode(13,INPUT);

void loop()
{ 

if (Serial.available() > 0){         // Check serial buffer for characters
        
    if (Serial.read() == 'r') {       // If an 'r' is received then read the pins
    
for (int pin= 0; pin<=5; pin++){      // Read and send analog pins 0-5
    x = analogRead(pin);
    sendValue (x);
    }

for (int pin= 2; pin<=13; pin++){     // Read and send digital pins 2-13

    delay (5);                        // add a delay to prevent crashing/overloading of the serial port

void sendValue (int x){              // function to send the pin value followed by a "space". 
 Serial.print(x);

The Task

  • Make sure you do the above. Not just once, but a number of times through the week. At least twice. You need to do it enough so that you feel reasonably comfortable and confident.

  • Clearly, I don't want you to submit your Arduinos. That means you need to submit some documentary evidence that you've completed your task. The most obvious way to do this is to submit some sort of video of your task working. If you can't do this, take photos. Bear in mind that you'll get extra marks for 'added value', so try to adapt and make more interesting your files. Simply repeating what we've already done will get minimal marks.

  • Zip or Stuff your patches, demos, photos, videos etc. into one file called your_student_number_"makingsounds" (e.g. 0504335_makingsounds.zip or 0504335_makingsounds.sit), include a readme with your name and student number and, if necessary, how to use or just open the patch, and submit the whole thing here.

  • On Macintosh, zip or stuff your patches by selecting the relevant files and/or folders and right-clicking/control-clicking on them, choosing 'create archive'.

The Projects

The projects and tasks are designed to help you through the various courses and materials that you'll have to deal with, and also to provide an active and practical element to what could otherwise become a rather dry and technical exercise. Tasks are small exercises - you may be asked to complete one or two per week. Projects are larger and carry a higher percentage of the mark. We will undertake two, three, four or more projects and tasks. The final project is usually an individual choice project, and will be worth significantly more than the others in terms of percentages in your portfolio. We will usually try to set aside a time to perform the projects in a public setting.
