I'm following Bela and Pure Data digital output tutorial. I'm doing everything as instructed in the tutorial, except I don't use the same resistor value, I tried 100-300 ohm resistors and one with 10k ohm. From P9/6 digital out I could get the light on LED but from P9/12 not.

What's P9/6 ? any value between 100 and 300 ohm should work; 10k definitely not. Can you show your code and your wiring?

Hey, I fixed it. I was missing to initialise digital pin 17. Thanks for the quick response.
