Delay before each led lights ? Answered
I'm using: 12V supply, 3mm or maybe 5mm blue leds 3.1v (20mA) (288 pcs) 470ohm(?) resistors(288pcs) I want one led to light and stay lit, then I need a 6 hundredths of a second delay before 2nd led lights and stays lit then delay and third light, and so on, and so on. All lights to remain on as it goes... and until completed... then all off in order to begin a new cycle. (Approximate cycle time is 20 sec to light all 288 leds) Trying to create the illusion of handwriting with leds.What capacitors and other resistors do I need to cause the delays? Wiring diagram plz. I'm a newbie. What size Fuse and its location? Thanks for not slapping me around to much. And thanks for helping.
