Basic blinking circuit design
Basic blinking circuit design
(OP)
For a miniature model set, I'm trying to make a 3-way (red, green, and yellow) traffic light blink on and off using a basic circuit design.
Green light: Turn on for 5 sec then turn off for 3 sec
Yellow light: Turn on for 5 sec then turn off for 3 sec
Red light: Turn on for 5 sec then turn off for 3 sec
The small lamps are 12 to 16VDC. Was trying to use simple capacitors and resisters
Having problems making it all work. I'm I missing something? If I can rig-up a simple "one lamp blinking circuit" using these components, I'm sure I can figure it all out. Need Help!

RE: Basic blinking circuit design
Whiole not hard..using discrete parts won't be real easy either since only one light should ever be on at the same time. The standard chip people will suggest is the ol' 555 IC but this is probably going to require 2 or three of them and their required CAPs and resistors. Just caps and resistors won't do it.
If you aren't into rolling your own uProcessor solution look at a PICSTAMP.
For about $30 you can get everything you need. You could run crossings and streetlights etc too.
