Okay. I've designed the schematic.

For the 10MM LED eyes, i'd go with this:

If i understand correctly, the lower eyelids don't need to blink so you could just connect them like this:

And for the Upper eyelids like this

Now, i would use a MOSFET to control the eyelids. You could just hook up the eyelids directly to an output but i think they'd draw too much current, most IO pins can only provide max. 40mA. As for the blinking, i could provide you with a schematic on how to let them blink at an even rate but randomly would be much harder. For the random blinking i'd go with a microcontroller. If you have an atmega168/328 and arduino to use as ISP i could write the code and help you program it.

Niek.

@ niek : OK.I follow what you are doing. I thank you so very much for your help!!!!! As for your sugestion of using a micro controller. I do have an Arduino Uno in my parts drawer.Unfortunately I haven't been able to learn the programming yet!!! I keep reading how everyone seems to say how easy it is to learn.................................... I guess this old mind of mine just doesn't learn easily anymore! I think I saw in one of your eariler posts that you use an Arduino. Is this correct? I don't want to impose on your good will but........................ How difficult would it be for you to write a sketch for the upper LED's to blink ramdomly? I'd completely understand if you don't have time to do it! I kind of hate to use a whole controller just to acomplish the blink! I guess it would be easier to just add the LED's to the EZ-B!!!! Do you have any suggestions on resources that might enable me to more easily learn Arduino programming?????? I've gone to the Arduino home page, as well as a website: Adafruit Ind, that offers tutorials. I have to consider that at my age I may not be able to learn. Thank you again for your help. I really appreciate it.

I hate the word 'age', anybody can learn arduino. I learned by adapting and combining existing sketches. If you'd like to start learning it, i could link you some great tutorials (i think adafruit is great but i found even better)

I program a lot for my Arduino. I could write the code for you, shouldn't be that hard. Did you know that when you programmed the arduino you could take out the IC to have it work as standalone? The IC's are only about 4 bucks in stead of 30 for a whole arduino. You could get the IC's power from the ez-b since it takes 5v.

If you're in, let me know.

I absolutely am in!!!!!!!!!!!!!!!!! I'd really like to learn so I can have more technogoly available to me. I've always been keen on learning. I don't think a person should EVER stop trying to learn!! Even though I have obstacles to overcome I hope I never get to a point that I can't learn!!!!!!!!!! I did not realize that the IC could be removed and used stand alone!!!!!!! An investment of $4 sounds very inticing!!!!!! I have a number of projects I'd like to do, and not having to buy a micro controller for each one sounds great!!!!!!!!! I also bought a micro meastro from Pololu, but havn't been able to learn how to program it either. Have you ever tried using one? You don't know how much I appreciate all of your help. You are a very, very nice young man! Your parents are no doubt very proud of you! I look forward to this new endeavor! I hope you will be patient with me as I'm just starting my recovery,and I have difficult periods. I am looking forward to this new endeavor.

Hey Lloyd as I have gotten older I have found when I'm learning something new I need to really stick with it for a while and concentrate on just that. After I have learned the basics of it then I can go back to doing other things . One of the IT guys at work said c# is really easy but as of today I don't know because I know "0" about it and have limited functioning braincells left ! So I guess we will learn together and if some of you that do know, could point us to where to get started that would be great. My personal problem is reading. I'm a bit dyslexic and it's like torture to try to read manuals . Sometimes I have to read something 5 times to understand the point that they were trying to get across. oh well ! J.W.

@ J.W. : I find it quite encouraging to discover other guys my age interested in robotics, etc. A good sign that we may be gittin' on in years , but still in there tryin'. Tecnology has grown so fast in our lifetimes and, I personally, am very pleased to be able to understand and use it! I agree with your sentiments....................we can help each other learn all this wonderful stuff. Hang in there my friend. BTW; whats your age and location?

@ BC : Are you following along here? Jump in an hang on! Your age and location?

@ALL - I too would be interested. I'm almost 52 and programming was never a strong suite. I've had no education in any of this, I just sort oftry stuff out and get alot of help from guys like you. I have a couple of Arduino duellinova boards I have never even taken out of the package as I don't even know where to begin. When I found the EZ-B it was so much easier to get things moving right away. But I would like to do some imbedded tasks with the arduinos. Any help would be fantastic! I live in the Norfolk, VA area.
