I used this code above for my arduino mega and connected the wires correctly to the right pins and all I am getting is a blink on the screen and then its blank with the back light on. I was wondering if anyone can help me with this
never mind I figured it out. with the shield on the back you are able to change the contrast of the display. that is why the screen was blank. If you are having the same problem let me know I can help you with this device
I used this for the library and work perfectly fine
