 Bigger Bigger  Smaller Smaller  Reset Reset

I bought a 5v from sparkfun. I wired everything like the schematic here : http://arduino.cc/en/Tutorial/LiquidCrystal, and triple check it. It's still not showing any text even after messing around with the pot.
Does any have any problem like I do?


These are two different LCD just to make sure it's not the LCD that is broken.

The green wire is connected to D0 instead of to E.

I'm not saying that this is your only problem but there is no 'maybe' involved here.
