I'm using the Arduino to max for dummies to read multiple sensors over in Max/Msp.

Firmata was not my choice because I never gotten it to work for properly..

I would rather upgrade and edit the ForDummies sketch and patch to make it work.

Does anybody know how to implement an I2C Luminosity sensor in the code, so It can be read by Max/Msp.

And help or give tips about the implementation of DHT22 (library editing?) and or BMP280 sensor (also I2C)

Give me a direction on where to start with this.

This is the code for the max for dummies and the patch. So no search is needed.

The protocol for communicating with this sketch is:

- When setting a pin state you can write 0 (input),1 (output),2 (pwm)

- Example: [p 3 2] & [v 3 128] == Pin 3 is set to be pwm and addressed with 50/50 duty cycle (medium "speed")

(just send as char values from any program that can communicate with serial ports ex. Max/MSP)

- You´ll need "[" and "]" to start and end requests.

- Example: 7 0 == Pin 7 is set to receive a digital input (a carriage return is send to end request.)

- The board will only output through serial if an Arduino port is set to input.

int portregister[]={1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1};

if(explodedSample[0].equalsIgnoreCase("v")){

setPinValue(convertStringToInt(explodedSample[1]),convertStringToInt(explodedSample[2]));

else if(explodedSample[0].equalsIgnoreCase("p")){

setPinState(convertStringToInt(explodedSample[1]),convertStringToInt(explodedSample[2]));

SERIAL INPUT:
  - set pin state (p) og set pin value (v)
    - When setting a pin state you can write 0 (input),1 (output),2 (pwm)
  - set pin number
  - set value
  - Example: [p 3 2] & [v 3 128] == Pin 3 is set to be pwm and addressed with 50/50 duty cycle (medium "speed")
  (just send as char values from any program that can communicate with serial ports ex. Max/MSP)
    - You´ll need "[" and "]" to start and end requests.

SERIAL OUTPUT:
  - pin number
  - value
  - Example: 7 0 == Pin 7 is set to receive a digital input (a carriage return is send to end request.)
  - The board will only output through serial if an Arduino port is set to input.
