Hello!
I am trying to make a switch that when a button is physically activated it starts an l.e.d. timer display that counts time, until the button is released.
How would I accomplish this, I have a small amount of experience with bread-boarding and soldering as a hobbyist, but would really appreciate not having to dig through a library of knowledge if a electronics sage out there could be so kind as to guide me in the right direction,
Thanks you.

You need to give us details regarding what you want to accomplish.

• Time range?
• Time format?
• Do you want to learn how to design your own?
• Do you want to use a microcontroller?
• Or do you just want a fast and cheap solution?
