LED Countdown Answered

HELP! My son is doing a project for one of his classes. He wants to have a group of 5 LEDs on a board about 3in X 3in 1 led in each corner and one in the center. The ones in the corners needs to light up one at a time for 30 seconds then the one in the middle needs to light up for 1 minute. Needs to turn on at the push of a button (preferably on the board, or by pushing the board) can run off AA or AAA battery or 9 volt. HOW DO I DO THIS? I would be willing to pay someone to do it! HELP


Its what they use on laminate counter tops. Sorry about the confusion. BTW this is what I make circuit boards out of (not exactly pcb, but its cost effective)


woah there, no need to pay anybody, all you need is a simple 555 timer circuit, I mainly posted this to bump you, but can you read schematics? if so I'll make a schemtic for you, or you could look around google. If you can't read schematics I'll just walk you through it, please reply! How much electronic knowledge do you have?

I have no Electronic knowledge! Serious Beginner! I would love it if you could walk me thru this!! Thank you so much!

I don't think it really helps you, but if you want to make your own boards use formica samples. You can get them for free from most hardware or flooring stores.

Maybe a 558 quad timer and a 555 would simplify things ?

yeah, a quad 558 would work better, just to be simple. Plus the extra 555 for the center.
