I am trying to create a time delay using a capacitor and reistor in my project at school it is a basket ball counter my input is a micro switch control is monostable 555 and 4026s, and my out put is a LED display.

T = R * C

Best to use another 555 for the delay

Click to expand...

I think a little more information is needed. T= seconds that the capacitor reaches 63% of the applied voltage, when R is in ohms and C is in farads.
