MULTIPLEXING 7 SEGMENT DISPLAY USING PIC MICROCONTROLLER

 Let us try to understand about multiplexing of seven segment display using PIC microcontroller to implement decimal counter which will increment 0000 to 9999.

Seven Segment Displays are arrays of seven “Light Emitting Diode” (LED) segments with additional decimal point (dp) which is also a LED. Each these segments are marked as a,b,c,d,e,f,g and dp.
