I am the person who wanted to create a project using MAX after learning the wonderful effects of MAX/MSP. 

but I have a something problem, And I'm having a lot of trouble with these problems. (so sad..)

The current state of my project is that the 'capacitive sensor' works well on the arduino, and this value can be seen on Arduino's serial monitor. And this value (serial) is being matched at Max. However, even when I don't touch the sensor, there is still a problem with sound output, and only one of the three sensors is working. 

I hope that sensor values will not be accepted if I do not touch the sensor, and that all three sensors will work on MAX.

And I found and followed a video clip similar to what I wanted to make, but I couldn't do some coding because of poor quality.

MAX:MSP CODING SCREEN SHOT.png

CapacitiveSensor yellowCapSense = CapacitiveSensor(4,8); // 

CapacitiveSensor redCapSense = CapacitiveSensor(5,10); // 1M resistor between pins 5 & 10, pin 10 is sensor pin, add a metal surface there

CapacitiveSensor greenCapSense = CapacitiveSensor(6,11); // 1M resistor between pins 6 & 11, pin 11 is sensor pin, add a metal surface there

long yellowCapVal = yellowCapSense.capacitiveSensor(50);

long redCapVal = redCapSense.capacitiveSensor(50);

long greenCapVal = greenCapSense.capacitiveSensor(50);

Serial.print(yellowCapVal); // print sensor1 text

Serial.println(" "); // print sensor1 output

Serial.print(redCapVal); // print sensor2 text

Serial.println(" "); // print sensor2 output

Serial.print(greenCapVal); //print sensor3 text

Serial.println(" "); //print sensor3 output

To sum up, the problem I want to solve is as follows.

1. Only the first sensor works, and I want to operate all three sensors.

2. The first sensor that goes on sound continuously even though it is not touched.

I would like to get a lot of help from you, and I would really appreciate your help. Please help anyone who has ever done such a project or is familiar with it!

Here is help for the trouble that makes You a lot of problems :

Serial.print(yellowCapVal); // print sensor1 text 

Serial.println(" "); // print sensor1 output 

Serial.print(redCapVal); // print sensor2 text 

Serial.println(" "); //print sensor3 outpu

Serial.print(yellowCapVal); Serial.print(" "); 

Serial.print(redCapVal); Serial.print(" "); 

 should be implemented only on last item of the serial stream,

otherwise You will allway get a single value output

Here is help for the trouble that makes You a lot of problems :
change this :
Serial.print(yellowCapVal);  // print sensor1 text     
Serial.println(" ");  // print sensor1 output 
Serial.print(redCapVal);  // print sensor2 text     
Serial.println(" ");  // print sensor2 output
Serial.print(greenCapVal); //print sensor3 text
Serial.println(" "); //print sensor3 output
into :
Serial.print(yellowCapVal); Serial.print(" "); 
Serial.print(redCapVal);  Serial.print(" "); 
Serial.println(greenCapVal);
-------------
The explanation :
println should be implemented only on last item of the serial stream,
otherwise You will allway get a single value output
from zl group in max patch.


I'll apply what you've told me when I have time!

So, is there any problem with my Max's coding?

In addition, I want to make the piano sound with Max. 

Can you tell me if you know any Command and Function In max?

Thank you so much your opinion!!!! :)

I can't say if there is any problem with Your max coding,

I have no time to troubleshoot other people's projects.

To make piano sound with max, there are several options,

Built in synth - that microsoft wavetable synth,

You are welcome.

To make piano sound with max, there are several options,
depending on OS as well.
Built in synth - that microsoft wavetable synth,
on Mac AU DSL synth.
Or use vst object with some plugin.


I've modified the aduino coding, as you said, and one of the three pins doesn't work. I'm going to put up the modified code. Can you give me some feedback?

Please post both code and max patch.
No screen shots.
And which pin does not work.
