Have you looked at XBee? These do work and have UARTs plus more.

I have the XBee2 Development kit from digi but haven't looked into using it as it seems like it might be overkill, plus I think a module is around $19, would need 2, which is pretty pricey for this particular project, particularly if I have to replace the transmitter every now and then for getting banged up in my pocket...will try it if you think it's best for this project, but was thinking something that would be close to what car key fobs use. Not sure what they use though as far as protocol.

 

Nice job on the 7 segment displays! I want to make a few of them now!!

Do you have a circuit diagram or proteus circuit created for this project?
I would love to see it or simulate it
Thanks

 

not yet as it's still in the design process, but I am very close. I finally have the transmitter and receiver working today but have some bug in my pic code for the scoreboard controller. I might put that development on hold for now to make a PCB as my breadboard has gotten quite messy and could be the source of some of my problems. I'll post a picture so you can see what I mean

 

Hello to all of you.....
This is my first time to post in this website and i'm hoping that someone will help me about our project.
Our project is aboout a manually operated scoreboard... Its just like a 7 segment led but the dimension is 7 by 10, each segment must be connected to individual switch. If you have a schematic diagram in connection to this project can you gave me a copy or send at my email ad. This is my email ad nkarenjoy@yahoo.com
All you're comments are highly appreciated.
Thank you...

 

Good day to all...
I would like to ask if somebody have a schematic diagram about a manually operated scoreboard. Its feature is simillar to the project made by norlyn...
Please help me about it...
Youre help is highly appreciated....
I'm hoping for your help....
Thank You very much....

 

Norlin,

Did you ever finish your scoreboard? If you did can you send some Pic's?

I did finish it, however I can't find it at the moment, once I find it in my over cluttered house I'll try to remember to post some newer pictures. It basically looks like the pictures I've already taken but with a plexiglass box around it.

 

Sounds like you guys have it figured out, but for what it's worth, i'll throw in my 2 cents.
I do a lot of LED work and have always diffused them by hitting the very tops on an upright belt sander. Just hold them in your hand and sand off about 1/8".
This is based on a 10mm LED. The ones I use are minimum 140,000 MCD with a 7 degree light spread. So after I sand them, the brightness and the 7 degree spread works out real nice for a diffused finished product.

I also want to say thanks to Norlin for posting all his efforts with the scoreboard project. Very impressive. If you ever get it on paper with your code, I'm sure many of us, including myself, would love to play with it.

Anyway, have a good xmas all.
