hello everyone can any body help me to do these:
when I press the switch on the seven segment display become counter like this 1,2,3,4,5, etc.. the when I press the switch off the seven segment display become count down like this 0,9,8,7,6,5, etc.. I want it become responsive for example I press the switch on it will count like this 1, 2, 3, and then when I press the switch off automatically it will count like this 2, 1, 0. I hope anyone can understand what I mean, sorry for my wrong grammar, thank you 
using millis
I hope anyone can understand what I mean
No, because you posted no code and said nothing about how the switch is wired.
Some questions for you :
Do you know how to read a digital input ?
Do you know how to show a number on the 7 segment display ?
How many digits are displayed ?
Should the counting happen whilst the button is held down or should the number only change when a button becomes pressed ?
If the first, then how fast should the counting happen ?
What should happen when the count reaches 0 or (assuming only 1 digit) when it reaches 9 ?
What should happen if both buttons are pressed ?
What have you tried so far ?
Hi,
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Can you please post a copy of your sketch, using code tags?
