  2. button to add a light and a button to take one away???

    in Electronic Projects Design/Ideas

    Posted

    Probably pretty odd of a thing to make but...

    I am in the need to make a small thing that has a row of 10 lights (LEDs etc) and with 2 buttons and a speaker giving a tone when one of the buttons is pushed.

    Button A would turn on one of those lights. hit the button again and it would add a second light and so on and so on, to a max of 10 lights. They would stack next to each other from left to right (from first light to the tenth light)

    Button B would simply reverse the and take away the last light given to the order.

    Maybe a 3rd button that would to just reset the lights (no matter how many lights are up).  but not needed at all, just handy I guess.

    Speaker would just give a beep or buzz or something each time the add a light button is pressed.

    Here is a link to a diagram I did that kind of explains better what I am trying for. I hope it helps. http://images.elektroda.net/75_1179456614.jpg

    Well if anyone know if this is a possible thing to make, can you let me know.  I can then at least start to research it. 

    heh! It has been years sense college electronics class.  I should be able to pull out my book some where in storage. :) I guess I really didn't have much to do this weekend anyhow. :)

    Well best wishes and thank you everyone for your time.

  4. Ornament Gift with Color LEDs Design help?!

    Hello Everyone and thank you for your time in reading this.

    I have a year of electronics in college but that was more then 18 years ago and I have forgotten probably half of it.  So please bare with me. 

    A few years ago I purchased this little Christmas Ornaments that you plug into the little light bulb sockets on the christmas lights on the tree.  I really do like them and had the idea of making some for girfts next year. 

    These lights only have a single blue LED in a clear plastic ice cute guy.  I was hoping to make something a little more fun with more LED colors that sort of phase into the other colors kind of slowly with an small overlapping in color period.  Maybe 3 colors... heck... maybe 4.... lol or just maybe Red and Green colors.  I guess I am not too picky. 

    I would guess Christmas lights run on a 110VAC here in the USA.  So I am not sure how this could be achieved safely with LEDs and some Diodes and maybe with some capacitors.  Maybe I am way of base.  Maybe I am needing some kind of chip for this task. 

    what ever I do I would like it to 1) be small to fix correctly if possible. 2) cheep would be second best. 4 kids make the pocket book small with my budget.  These are not all required but would be nice.

    So with this all said, would anyone have any advice on how I could get started trying to figure out this thing.  I know if I dont get this going now I will NEVER get them done before next Christmas.

    Well thank you EVERYONE for your time again.

    Best Wishes all
