In Arduino based embedded system design, the Liquid Crystal Display modules play a very important role. Hence it is very important to learn about how to interface LCD with an Arduino of 16×2 in embedded system design. The display units are very important in communication between the human world and the machine world. The display unit work on the same...
LCD display at the most basic level, most (but not all) liquid crystal displays change the polarization state of light passing through the liquid crystal layer. The competition between the boundary conditions and the applied electric field controls the geometry of the layer. Generally, for this type of LCD, nematic liquid crystals are used, and special coatings are applied on...
