Data that is processed mikrokontroler data hexa, to be shown on seven segment we can use dekoder hexa to the sevent segment or through the conversion program, for konveri, we can use the system look up table program we need a conversion table, table is as follows:
Place the module with mikrokontroler seven segment connecting module on port 1 and 3, do not look up inverted. Seven segment that is in use CA (Common Anode), thus need to be given to set the logic 0.
