Nokia5110

[santiago16]

Hello,
I bought a couple of stuff from this amazing store , I was very happy with the Nokia LCD and yesterday I read all the tutorial and I soldered the pins, mount all the breadboard circuit... But now I'm a litle sad because one of my two LCD is not showing anything... It is disspointing because one of them is working perfect and showing the stars from the demo software... but the other one is just showing the backlight. I double check in the one is not working that everything was soldered ok... I take a photo but is not a good one...

VCC is 3.3... I'm using the voltage shifter to talki with the arduino... I'm using all the pins... one LCD is working OK so I'm sure is not my breadboard... Is there anything else I can check?


Thanks

Can't see anything in the photo. Try to get one with better focus. Also a photo showing all the connections on the breadboard and to the Arduino.

Hello,

As I said, I bought two LCD, so this those are the photos of my LCD that is working OK:

And the only thing I did is take this off and put the other one... and I only get the screen on:

Also, thank you very much for writing back

I found something very strange... in the LCD that is not working I tested continuity between the lower points and the higher points... I mean 1 with GND... 2 ... with VCC... etc... and I had continuity in all but not between DIN and 4... :O!!!! This looks very strange!!! I suppossed that something is wrong in here I put a cable from pin 4 and didn't use the DIN, and guess what!!! THIS WORKS!!!!! So I had two options... I did a bad solder in pin 4 or something was wrong with the circuit... and offcourse what was wrong was my solder in this pin heheeh (The strange thing was it looks good) !!!

Sorry for bother... and thank you so much for writing back... I'm getting in love of this store!!!!! The only thing I will recommend is to sell more things that maybe are not strange or very cool (3.3v regulator is one of this...)... but are necessary with this kind of projects. For example I live in Colombia. And when I need electronics stuff I choose the EEEUU store that has more things that I need... to only buy in 1 place...

Great that you got it working, and thanks for the follow-up.
