Connecting buttons and other elect. components

I have a project for Bela on RNBO and right now I'm using only Trill sensors for simplicity, but two of them I use as a buttons, and I would like to change them to real buttons. How could I do this? Is this tutorial compatible with RNBO? https://learn.bela.io/tutorials/c-plus-plus-for-real-time-audio-programming/analog-i-o/

you can connect real buttons to the digital inputs using the diagrams for buttons you find here https://learn.bela.io/tutorials/pure-data/connecting/digital-input/ and that will make it available as a digital input in the Bela program.

giuliomoro thanks a lot!!!
