Hello,
I was wondering what you guys use for a trimmer pot for an adjustable Contrast on the 16x2 LCD useing the hitachi HD44780 chipset. I have been told a 50k should be used does this sound right? Also i have tried to search for cheap trimmer pots on digikey but cannot find anything that is not expensive, i want to keep the cost down to .15cents/per if possible. anyone have any recommendations?
Thank you!
