Nokia 5110 not working

@user55002 looks like you've wired the display up the wrong way...

The tutorial says:

...place the Espruino Pico on the breadboard with the USB connector facing left, and then place the LCD directly above it, aligned to the right (so the pin on the Pico nearest the USB connector should not be connected to anything).

You've put the USB connector facing right in that picture...

It should look like in the picture below... Can you give that a try and see if it works?
