I purchased this LCD: seeedstudio.com/depot/index. … 164&page=1
I have hooked it up to my Arduino and have been doing some testing with the LCD Library that seeedstudio provides and I’ve found something very strange, when the number 8 or 9 is displayed on the screen, the LCD back-light dims.
I also found when using the default Arduino LCD Library, the backlight would completely turn off when a 8 or 9 was displayed on the screen, however everything else seemed to work fine.
Any idea if I have a faulty LCD or what?
