This presentation is exhibitting how to does a LCD works and how to use such LCD in you embedded system or robotic project using AVR microcontroller Series. The complete procedure of using 16X2 Character LCD is given Digital Multimeter. A digital multimeter (DMM) is a multifunctional meter that displays its electrical quantitative values on an LCD screen. A digital multimeter much like an analog meter, it is able to read voltage, current, and resistance. What makes a digital multimeter differ from the analog meter is its ability to display measured What is a Digital Multimeter. A digital multimeter or DMM is a test equipment used for resistance, voltage, current measurement, and other electrical parameters as per requirement and displaying the results in the mathematical digits form on an LCD or LED readout. It is a type of multimeter which functions digitally rather giving an analog output. Electroluminescence. Electroluminescence ( EL) is an optical and electrical phenomenon, in which a material emits light in response to the passage of an electric current or to a strong electric field. This is distinct from black body light emission resulting from heat ( incandescence ), chemical reactions ( chemiluminescence ), reactions in a For capacitive touch screen panel, lower resistance is demanded to improve input performance. Also, crystallized ITO layer is required for durability and optical properties. We report on the ITO LCD is an acronym used for Liquid Crystal Display. It is basically a display technique in which liquid crystals are used in order to produce an image on the screen. In this section you will read about the construction, working, advanatges, disadvanatges and applications of LCD. .
