Maxuino works perfectly fine with max 5, but what about max 6?

Does anyone have good/bad experiences with maxuino and max 6?

Are there other ways of connecting an arduino uno to max and get ALL analogue inputs into max while still being able to control LED lights via the PWM outputs? (The code seems pretty complicated to do from scratch from both the max and the arduino side ...)

maxuino-and-max-6

Hmm ... I downloaded max 6, and maxuino doesn't seem to work in max 6.

Is there an easy way in max 6 to both get analogue input data from the arduino _and_ at the same time control LEDs with the PWM output from max?

I have max6 and have got Maxuino to work ok with it. There is a PWM function included in it but it doesnt seem to create the "fade" effect on the LED's that you would get doing it using arduino code. Im trying to do something similar in my project which I have just asked about in the forum.

Is here a way that I can add some code to the SensorBox.pde file, so that the arduino can receive messages from max to control the pwm pins on the arduino uno?

If you're just looking to fade LEDs, why not start from this example sketch and use the included Max patch?

Thanks for the suggestion with the Dimmer tutorial. Then at least the LED control problem is solved.

However, the arduino sensorBox code combined with the arduino dimmer tutorial code is still a problem, because data needs to be sent back and forth at the same time. I wonder if anyone has solved this problem? I am working on it right now, but it is quite complicated to do for a beginner in arduino code ... any hints/good advice?

There are other Communication examples that explain how to send data both ways. 

http://arduino.cc/en/Tutorial/SerialCallResponseASCII

http://arduino.cc/en/Tutorial/SerialCallResponse

 show how you can send multiple bytes from the Arduino, and have it receive something from Max.

Now I am trying to combine the serialCallResponse example with the dimmer example, and I almost have something working (see below posted codes). However, it looks like the LED is getting updated to full strength everytime I send a new slider value to the LED from max ... what do I do wrong in the arduino/max code?

int firstSensor = 0; // first analog sensor

int secondSensor = 0; // second analog sensor

const int ledPin = 9; // the pin that the LED is attached to

pinMode(2, INPUT); // digital sensor is on digital pin 2

establishContact(); // send a byte to establish contact until receiver responds

// if we get a valid byte, read analog ins:

// read the most recent byte (which will be from 0 to 255):

// read first analog input, divide by 4 to make the range 0-255:

// read second analog input, divide by 4 to make the range 0-255:

thirdSensor = map(digitalRead(2), 0, 1, 0, 255);

int firstSensor = 0;    // first analog sensor
int secondSensor = 0;   // second analog sensor
int thirdSensor = 0;    // digital sensor
int inByte = 0;         // incoming serial byte
const int ledPin = 9;      // the pin that the LED is attached to

void setup()
{
  // start serial port at 9600 bps:
  Serial.begin(9600);
  // initialize the ledPin as an output:
  pinMode(ledPin, OUTPUT);
  pinMode(2, INPUT);   // digital sensor is on digital pin 2
  establishContact();  // send a byte to establish contact until receiver responds
}

void loop()
{
  byte brightness;
  // if we get a valid byte, read analog ins:
  if (Serial.available() > 0) {
    // read the most recent byte (which will be from 0 to 255):
    brightness = Serial.read();
    // set the brightness of the LED:
    analogWrite(ledPin, brightness);
    // get incoming byte:
    //inByte = Serial.read();
    // read first analog input, divide by 4 to make the range 0-255:
    firstSensor = analogRead(A0)/4;
    // delay 10ms to let the ADC recover:
    delay(10);
    // read second analog input, divide by 4 to make the range 0-255:
    secondSensor = analogRead(1)/4;
    // read  switch, map it to 0 or 255L
    thirdSensor = map(digitalRead(2), 0, 1, 0, 255);
    // send sensor values:
    Serial.write(firstSensor);
    Serial.write(secondSensor);
    Serial.write(thirdSensor); 

void establishContact() {
  while (Serial.available()
    Serial.print('A');   // send a capital A
    delay(300);
  }
}

OK, a tiny change in the code makes it work a bit better, but the LED light is still a bit flaky when the value is changed.

... I am not sure if this is the right way to do it, but at least close to working.

void loop()
{
  byte brightness;
  // if we get a valid byte, read analog ins:
  if (Serial.available() > 0) {
    // get incoming byte:
    inByte = Serial.read();
    // read the most recent byte (which will be from 0 to 255):
    brightness = Serial.read();
    // set the brightness of the LED:
    analogWrite(ledPin, brightness);
    // read first analog input, divide by 4 to make the range 0-255:
    firstSensor = analogRead(A0)/4;
    // delay 10ms to let the ADC recover:
    delay(10);
    // read second analog input, divide by 4 to make the range 0-255:
    secondSensor = analogRead(1)/4;
    // read  switch, map it to 0 or 255L
    thirdSensor = map(digitalRead(2), 0, 1, 0, 255);
    // send sensor values:
    Serial.write(firstSensor);
    Serial.write(secondSensor);
    Serial.write(thirdSensor); 

You had it better with the first Arduino sketch.

Originally you were sending a 65 in addition to the value you wanted. Not sure what you were trying with that second sketch.

//and use that byte to change the LEDs brightness:

int firstSensor = 0; // first analog sensor
int secondSensor = 0; // second analog sensor
int thirdSensor = 0; // digital sensor
int inByte = 0; // incoming serial byte
const int ledPin = 9; // the pin that the LED is attached to

void setup()
{
// start serial port at 9600 bps:
Serial.begin(9600);
// initialize the ledPin as an output:
pinMode(ledPin, OUTPUT);
pinMode(2, INPUT); // digital sensor is on digital pin 2
establishContact(); // send a byte to establish contact until receiver responds
}

void loop()
{
byte brightness;
// if we get a valid byte, read sensors
//and use that byte to change the LEDs brightness:
if (Serial.available() > 0) {
// read the most recent byte (which will be from 0 to 255):
brightness = Serial.read();
// set the brightness of the LED:
analogWrite(ledPin, brightness);
// read first analog input, divide by 4 to make the range 0-255:
firstSensor = analogRead(A0)/4;
// delay 10ms to let the ADC recover:
delay(10);
// read second analog input, divide by 4 to make the range 0-255:
secondSensor = analogRead(1)/4;
// read switch, map it to 0 or 255L
thirdSensor = map(digitalRead(2), 0, 1, 0, 255);
// send sensor values:
Serial.write(firstSensor);
Serial.write(secondSensor);
Serial.write(thirdSensor);

void establishContact() {
while (Serial.available()
Serial.print('A'); // send a capital A
delay(300);
}
}

maxuino and max 6 ...
