I want to try and build an LED clock. The idea is to have a sequence of LED`s that light up one at a time at a regular time period over a pre-definied time. Once the all the LED's are on then they start to go off one at a time. I thought I'd just try and get 5 LED's to light up one at at time first. My problem is i have never designed any form of circuit. I know how LED's , capasitors, resistors and inductors etc. work, but to try and integrate these components into something useful is beyond my current understanding so I'm asking for a little guidence. HOw do you get a sequence of LED`s to light up one at a time?
