how to make 3 LED's flash at different times? Answered

Hello, I am looking to make 3 LED's flash at different time intervals. It doesn't matter in what order they flash. I have little to no experience in electrical, but am willing to give it a shot. Can someone please tell me what I would need to get in order to make this happen? Also, a circuit diagram would be good if anyone has one. Thanks.

there are various key chain toys that do exactly that. use one of them as is maybe you can use the circuit from a digital clock - wire the leds to few of the 7 lines that make the seconds digit. a bit unsure if it works with lcd clock (leds take way more current and voltage than the lcd screen) with standard components you need N555 timer chip + resistors and capacitor to bring it to life + a counter chip
