Design a LED SIGN ....

i have electronic experts your project very simple. let's start Thank you.

Hello, Please check your PMB. Thanks Have a awesome day..

Hi, I am able to fulfill your requeriments on the fastest time with the highest quality over all the bidders. I also offer you a high-quality device with extended warranty and post-delivery support service.

Sir, I am ready to design your LEd.

I can do it.

Hi !!We are a team of electronic engineers and we do R&D for private companies..We can do your project with high precision and with high priority..we are new to this website.

I am an expert.

Because of the nature of your project, it is actually quite easy. I have been working with electronics and microcontrollers for 15 years and have made many things like this. I would be happy to send you some pics of the various things I've made). I would use a small microcontroller as your base (cheaper than discreet parts). This would switch between the two sides (colors). You would then simply have two light-groups, run in parallel with a resistor (probably a 220) with each. You would also need a simple transformer so you could plug it into the wall. The schematic is easy, the PCB design is easy. I would use EAGLE for the design and GERBER files. You would need to send the PCB out for fabrication, but I know several places that will do it at a discount. The entire thing shouldn't take more than a day or two.
