------------------------------ Click "Show more" ------------------------------------------- A tutorial on interfacing LCDs (liquid crystal displays) with Arduino. We take a look at libraries and the role they play...and the potential issues, errors and troubleshooting involved. We look at several types of displays but concentrate on the 4x20 Sparkfun serial enabled LCD display.
