To build this I needed a WiFi-connected computer a Raspberry Pi is an obvious choice plus a display that is easily visible in a variety of lighting conditions. These displays typically have a USB socket for charging and programming, and appear to a PC or Pi as a virtual serial port.
They are highly visible, and of course, can be customized with a variety of messages, graphics, and effects like flashing, scrolling, wipes and fades.
We carry a wide variety of sizes, colors, and types of programmable led signs to cover just about any need. The programmable signs are lightweight, durable, and easy to program.
Our scrolling signs come with either a simple "TV-like" remote control or computer software and cables to program the sign Check the individual product pages for details.
Once programmed, the signs have memory that will hold your messages for months, even with the power off. Installation is a snap, since each sign comes complete with brackets or other mounting hardware.
Several factors determine the quality and price of your sign.
The most important of these are brightness, pixel, pitch, matrix, and color: Indoor Scrolling led message display use a type of LED that is less bright than the ones used for windowfront and outdoor signs.
This is why an indoor sign is generally less expensive than other types of signs. When both light together, a third color is formed a red and green pixel lit together appear yellow.
The pitch for a sign is the distance, in millimeters, between each pixel. If you have a sign with a 15mm pitch, then means that there are fifteen millimeters from the center of one pixel to the next closest pixel.
A tighter pitch delivers a clearer picture, much in the same way that an High Definition Television has a clearer picture than an old tube style TV. The matrix represents how many pixels high, and how many pixels wide, your sign is. A sign with a matrix resolution of 16h by 96w means it has 16 pixels from top to bottom and pixels from left to right.
Generally, a sign needs 7 or 8 pixels of height to display one line of text, 16 to display 2 lines, 24 to display 3 lines, and so on.
If you are using 7 or 8 pixel high lines, a width of 60 pixels allows you to display 10 characters, 80 pixels allows for 13 characters, and so on. And, with graphics instead of words, the higher the matrix, the more realistic the graphics.
As described in the "pixel" section, 3 color signs require 2 different colors of LEDs, and full color signs require 3 or more different colors of LEDs. Thus, color signs are generally more expensive than single color signs.

So in my application it can display “All OK” statically. An arduino library, written to drive popular HUB12 based single color P10 LED display panels. It uses TimerOne and SPI library of arduino.
