Max not reading Arduino data from serial object (macOS)
I'm pretty new to Max and I'm trying to hook up an Arduino with a potentiometer to control things within Max. I followed a tutorial and was able to make it work briefly, but now it doesn't and I don't know what's happened. I don't think there have been any changes between it working and not working. Very confused.
In the Arduino IDE's Serial Monitor, I can see the data. I turn the dial, the Serial.println() output goes from 0 to 255. But the serial object in Max doesn't seem to 'see' it. I checked the serial port info and it seems to be correct. port a. I've included pics of the patch and the Arduino code/IDE (including Serial Monitor showing the potentiometer data). Does anyone know what I'm doing wrong? I tried restarting Max but no luck. It just seems to have stopped reading serial data. Any help would be greatly appreciated..


Arduino IDE 2.0.0
Max 8.3.3
macOS Montery 12.4
MacBook Pro, M1 Pro
your patch should work, but don't forget to CLOSE arduino serial monitor
before initialising serial port in max.
Only 1 app can talk and listen to arduino board at a time
Ah, thank you! I had the serial monitor running in Arduino IDE. Doh. Forgot about that. I closed it and it's working fine now. Thanks!
