Your matrix should not be connected to Vcc. See the schematic here: https://tttapa.github.io/Control-Surface-doc/new-input/Doxygen/d4/d53/NoteButtonMatrix_8ino-example.html For 4 buttons, there is nothing to be gained from a matrix layout. Just connect each button between an input pin and ground. |
