Yes i figured just the way you do that connecting my positive end (with a resistor in between) to the one that says "+" and negative to "-" would work. But it didn't, and just as you suggest, i tried the other way around. And that worked. So that's where my confusion comes in. I guess it's just the manual where they got it wrong?! Because now i've wired it "wrong" and i got the display up and running, displaying messages and working perfectly.

I also noticed, in the page with the display commands, that you can turn brinking on or off. Guess that says a lot about the accuracy of the manual.

Thanks for your replies! smiley And if anyone has a different opinion, please let me know - if i'm wrong i want to know.

i'm sorry, i really don't understand the words you just typed... i learned this stuff in swedish so that might be the reason smiley-wink

Hey there,

First post, so I have an excuse to be a true noob smiley-wink

Actually i've done some electronics projects before and i would say i've got the hang of things beyond the basics. But... now i'm getting started with an Arduino project involving an LCD Display called ATM1602B. Manual can be found here:

Now, this really shouldn't be a problem and i've got it working, but to be honest i think the wiring should be the other way around. My problem is with the backlight power. It says "+" on the last pin. And "-" on the one next to it. The manual states that i should connect 4,2V to the "+" and GND to the "-". But if i do so, it's dark. If i go the other way around, it lights up... And i'm so confused that i refuse to go on before i understand why. If i can get this wrong, i must be misunderstanding something basic. And then who knows what mistakes i'll make once i start plugging other things in smiley-wink

Please, somebody enlighten me smiley-razz

This is great! I know it's been posted for a long time but just thought I'd show my appreciation smiley I'm considering making an own feeder and using a simple comb for the feed mechanism is a great idea i hadn't thought of.
