Hello again. My current question regards LED lights. I just want to turn them on and off. I searched the forum and all of the forum responses regarding LED lights were much more involved than the answer I need. I gather you use a servo control to do it. I've tried several different servo options, but none have worked to do what I need. I just want to turn them on and off. I have them connected to a digital connection D06. Maybe I should use an analog connection? Thanks.
The TIP circuit is very basic to be honest and isn't difficult to make. It'll also improve your soldering skills (it did mine!)
You wont be able to run 6 white LEDs from the signal port, white LEDs are usually higher current than other colours and sometimes you can't even run 1 on the signal current.
You could use a toggle and switch via a servo but that's a bit rough and personally I'd steer clear of it.
If you want a plug and play option you could use an Arduino Relay board (just search ebay for one). If you were in the UK I would send you a TIP circuit, maybe someone in the USA will offer that?
@Rich, see post #16.... I just did.

Wow! Thank you guys. Great ideas and help from all of you on this board. Alan, I will take you up on your offer. I'll send you an email.

Problem resolved mostly by Rich, the TechGuru, and Richard. I also appreciate Wolfie's and Jeremie's responses. I can only select one, so I will be using Rich's design with Techguru's kind help.
Craig
OK, How did you resolve the problem in the end. There were many options given to you. Curious minds like to know.
I mailed him a TIP120 circuit, based on Rich's tutorial but wired inline instead of strip board.
Alan
Yes. And thank you again Alan. When I receive the circuit and wire it in, I will report back on this thread. I'm sure it will work fine. When I said "I can only select one" I was referring to needing to report that the problem was resolved, but I was only allowed one choice of name, when in fact several folks helped me. I had received two email reminders to "close out" the thread. While I am going with the circuit that Rich designed and Alan built, the other suggestions were helpful to me as well. I am new to this, and helpful information is golden.
I received the circuit from Alan and hooked it up. Works fine for my LED display using the Digital Set function. Thanks Rich for the design and Alan (thetechguru) for making the circuit for me. Now on to my next step. This forum is very helpful. Guess y'all know that already.
