1.Mempelajari 7 segment LED Display.
2.Dapat configure, controls 7 Segment LED Display module CITS's NX-2000.
3.Dapat create a simple program that will be displayed on the 7 Segment LED Display.
2. Basic Theory
7 Segment meerupakan combination of 7 pieces of LED display dirangkaian a number. 7 segment consists of 2 types of the Common katode (katode linked together) and the Common anode (Anoda linked together), in this experiment used katode is common.
7 Segment LED Display is one part of the module CITS NX-2000 we can use the display to show the number of programs that we sent through a parallel module. To configure the system so we need a parallel module and the module 7 Segment LED Display CITS's NX-2000.
To create a display then the number we need segment (LED) that we need, and mengnonaktifkan segment (LED) that are not needed. For example, to create a number 1, then activate the LED b (D1) and c LED (D2), and disabling the other LED. Next pengamatannya table below the display output.
