Time delay LED Answered

I have something I want to make, but I don't know what I need, how to make it, or what it would be called. Essentially I would like to have a few LEDs on a programmable/resettable timer.


One LED would be programmed to say 3 minutes, 30 seconds from the 3 minute mark it would slowly start to light up then flash when it hits the mark. I would also like to be able to start/stop and reset the timer.

I need a couple of them, and wiring the LEDs are simple enough, it's the time delay that's throwing me. Any assistance would be great.

Look up the instructables on flashing LED projects. They use a microprocessor chip called an "arduino" which is simple to program and control a bunch of LEDs. The timing is set in the programming and you can have the LED blink or light steady. Good luck.
