                       Quick introduction 16*2 LCD  LCD means Liquid Crystal Display. We use LCD technology everyday in Watches, digicode display, and so on . Look around you, and check these small or great LCDs. There exist two big families of  LCD display:    *    Character LCD is based on a matrix of characters (columns x rows)    *    Graphical LCD , is based on a pixel matrix We can find a lot of printed circuit boards that include an LCD and the connectors to interface them with Arduino and other systems for cheap ,  nowadays. There is now a library included in the Arduino Core that is really easy to use. Its name is Liquid Crystal,   and it works with all LCD displays that are compatible with the Hitachi HD44780 Driver. This driver is really common . Hitachi developed it as a very dedicated driver,    that includes a micro-control...

Fingerprint Based Biometric Attendance System using Arduino Attendance systems are commonly used systems to mark the presence in offices and schools.
