Powering up LED for two secons

Post by RickDangerous » Fri Oct 29, 2021 7:45 am

Hello,

I'm looking for advice for a small project and thought this would be a good place to start. I need to make something that when powered up, will power up LED for 2 seconds or so and then turn off. It is probably pretty simple but I don't know where to start.

Any help would be appreciated.

I have not found a suitable solution on the internet so you are my only hope.

Thank you.
