Nokia 5110 not working

Hi - yes, you've got the display in slightly the wrong position:

Simply 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).

So you've got the display over to the left - but you need to move it one pin to the right.

... just to add it might also be worth checking that the pin strip is soldered to the board correctly? It's hard to tell from the picture but it looks like there might not be much solder on those pins, so one or two might not be making good contact.
