I am still a complete noob with electronics, not so noob with programming. I would want to just try stuff, but with electronics, i am afraid i mess up and screw up my parts. I was following this tutorial:http://arduino.cc/en/Tutorial/LiquidCrystal
I have those exact parts, and connected everything like the image, copy pasted the code and uploaded it to my Arduino UNO.
Now only the top row of the LCD is turned on, no message appears, nothing, you can just see it's green instead of dark blue. The bottom row is completely dark blue like it's turned off. The potmeter works, i can adjust the brightness of the display, but ofcourse, only for the top row...
Is it possible my LCD has a defect? What can i try to test if my lcd is defect?
Thanks in advance!
