it may be a matter of the confusing numbering: you seem to be using pin P8_30
, which is Bela digital 15. However, as the example mentions, Digital channels are numbered 11 to 26, which corresponds to
Bela's 0 to 15 digital channels.
so you need to add 11 to that number in order to obtain the corresponding number according to Pd. In fact, if you hover on the pin diagram, you will see for each pin what that pin number is in Pd parlance.
In practice, to use that pin you should have a Pd patch like this (untested):
