Now to understand the working consider a seven segment display is connected to a port so say we have connected a segment of display to pin0 b segment of display to pin1 a segment of display to pin3 a segment of display to pin4 a segment of display.
Pin10 or g to pin 8.
The seven segment display is infact a very simple device.
In our daily life we come across many displays like television smartphones computers traffic lights time counters digital watches washing machine etc we have different types of displays according to the use.
