I'm a rank newbie at 60+ years old LOL.
Tech by trade so I think I can 'get' this stuff.
I saw a program in the MagPi a couple of months back - called PIPIN I think - shows the status of the GPIO inputs and outputs.
It uses the NPM packaging and I'm reading all this stuff and it isn't making much sense.
Can someone tell me how to invoke (run) the program ?
I've installed NPM and PIPIN and now I'm lost.
