Stop light cycler Answered

Hello. I have an old Stop light in my game room.  I would like to have a switch that will cycle the lights: R, Y, G, R, Y, G....etc. I would also like it to dim the lights and have a setting to pick one light at a time.  I have see cyclers but they are about $100.  Can I build one for cheaper?  The cycling feature is the most desireable.  I can dim separately and do without the hold feature if I have too.  thanks for looking.  Aaron

Here is s simple 3 color RYG ckt

Hi IC, thanks for the time you put into that. i will have to study Fro's web site below just to figure out what to do with it. lol. Thank you. Aaron

Cool thanks again. This project might have to wait until after Christmas but I know what is going to be on my Santa list.

Then Ill help you with simple code at the new year.

A microcontroller like arduino is overkill, BUT, it does offer the freedom to program any settings you want, from manual dimming to automated patterns.

It would be a simple matter to set up some high power leds switched on/off by the arduino.

Board: 20-40 dollars
LEDS: depending on brightness (won't need much indoors or it will drive you insane), about 20 dollars with driver circuits.
Power supply: Wall wart (preferably smps) around 7-12 volts. a few bucks at surplus.

I frollard. thanks for your reply. I guess I forgot to mention that I have no electronic experience at all. I can build just about anything and even wire a whole home but when it comes to an arduino, I'm lost. Not to say I'm not interested in learning. Hopefully someone can lay it out a little more. Thanks again. Aaron

Seriously, if you have the know-how to learn hot and neutral in house wiring, you can totally handle an arduino. I know it's scary because it has tonnes of tiny wires and traces; but they follow the same electricity rules as you would follow wiring a house :)

I really recommend the arduino website, they have the 'learning' section where you can preview the steps you'd take to set up simple circuits, the reference section to look up any code you might need, examples for everything imaginable, and forums to ask questions left unanswered by the huge resource.

Cool Frollard. I will check out the site. I love to tinker with stuff and fear I may have a new addiction if I get into these things. Thanks for your advice.

Well, here is an actual uP dimmer good project, granted it is more advanced thin you understand so I am putting a much simpler stamp lamp driver for you soon.

What are the bulbs in your RYG 110VAC 220VAC 12VDC ??

it is currently a stock fixture. The bulbs are the screw in type 110v AC. I have put in a low wattage because it really is bright. I put the lower bulbs so it just "glows" and doesn't light the whole room. I'm not opposed to changing these out for some led's. Thanks

www.picaxe.com board £6 easy to program. only £`1.80 all you need is the 08M chip.
