LED 16x2 Display NOT working

Post by whlatimer »

I did my best at soldering the pins for the LCD 16x2 blue on white display, but the unit fails to show any sign of life once I connect it to the breadboard and do all the wiring, including the potentiometer. I am dreadful with a soldering iron so the fault may lie there, but is there any way to confirm the LCD is even getting power? Any suggestions for my next move? Thanks.

Post a photo of your hardware and we'll see what we can find.

The usual "the LCD doesn't work" problem is that people forget to adjust the contrast potentiometer. It sounds like you've done that though, so now we move on to the hardware debugging.
