It's I think the most popular electronic circuit, but defeinatelly not the easiest. I've already bought all the necessary components to build one that uses NE555 integrated circuit. However, I do not know the basics of NE555, so could somebody help me pls?

That is, if you want to learn what all the pins are for. Unless, of course you want to find out about its internal circuit. if so, the link below shows the structure:

I hope it helps :-)

In my opinion, it's always best to check on the internet. I rarely use the NE555, so I left a really good link down below:
