7 segment led display counter.
Sketch broken down in sections explained part 4.
Added two buttons and modified sketch part 5.
Pin3 or pin8 or cc to ground through 100ω resistor.
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.
