Hi ! I have an idea, where I need a circuit, which can do the following: There is a constant 12v power input connected to A (in the picture) Then I need to have power to the diodes(LEDs) (1 and 2) for about 4 seconds, then they shall be "turned" off There will be a constant 12v power to A.. And the next time 12v "hits" connection A the process needs to be restarted... Diodes(LEDs) shall be "turned" on for 4 seconds, and then "turn" off How can this be done? If it's possible I need a complete "recipe" beacuse, im a complete newbie at this And sorry on my semi bad english.. Hope you guys can understand what I mean!
