robotics-university.com | Hello friends, today I will give an overview about one of display component in electronics world. Do you know what component is? Yes, you are right! That is liquid crystals display or LCD. In general, this component used by embedded systems development or hobbist to display data that has related with their projects, i.e. temperature measurement, ADC value, real time clock, and etc. On this article I explain about 16x2 character LCD module HD44780 from Hitachi (or compatible). See figure 1 for the visualization and figure 2 for its diagram block.
