Hi folks, I've recently come back to Max after a lengthy break and I'm trying to collect data from a light sensor as a simple stream of values in Max.

I achieved this a couple of years ago, but currently I'm having issues with Max reading the Serial object. Everything is fine in the Arduino Serial Monitor, it's just not making it's way across to Max.

Any thoughts or suggestions would be hugely appreciated! :)

Here's the Max patch (with the itoa sub patcher pasted into the main patcher for reference)

void loop()
{
  lightLevel = analogRead(A0);
  Serial.println(lightLevel, DEC);
  delay(200);

assuming you have the latest version of the Arduino IDE, and have selected the correct serial-usb port (dev/tty . . ., or COM3 e.g.), then all you should need is this:

If you're using an older board and IDE, then

does exactly the same. Then in Max just bang the serial object (serial a 38400; serial b 38400, or whatever) for the data.

Hi

Thanks for your reply. The IDE is up to date and the board is pretty new. Where exactly should the additional arduino code go - after Serial.println?

Additionally, it's going through port /dev/tty.usbmodem1421 and in Max it's set up as serial a 38400 (I can't see the reasoning in defining it as 'b') Cheers, TLR

Replace println with write and you don't need the 'convert' subpatcher on the other end:

void loop()
{
lightLevel = analogRead(A0);;
Serial.write(lightLevel);
delay(200);

Thanks, Medd! Worked a treat! :D Thanks also, N00b, for the initial help :)

Thanks for filling in the blanks medd - I was in a hurry, hence my concision
