Tell us about yourself!
Very good project. I did the same thing to my pirate radio, because originally the buttons are too small for my 90 years old step mother. She loves to hear tango and Chilean radios.
When I've executed the commands, my node.red went nuts and node.js doesn't answer...pi@raspberrypi:~ $ node -vbash: /usr/sbin/node: Aucun fichier ou dossier de ce type
finally worked with some adjustments. New version have some differences...thanks for the information....
Ok, I saw the other answer and then I made $sudo node -vv0.12.6seems to work now, let's continue....
