As our display is made up of seven Bi-color LED Matrices, we need an additional three output pins on the micro-controller to interface with the other three daisy-chained LED Matrices.

This kit comes with all through-hole components and someone with basic soldering skills should be able to assemble it without much difficulty.

The following are some of the projects built using this Bi-color LED Matrix Driver module which you may want to check out:. After all the kits are completed, they are connected together with the micro-controller as shown below LED Matrices not installed for better view. Here, we use the chipKit UNO32 micro-controller board which is based on the popular Arduino Open Source hardware platform to drive the display.

However, you may instead use any suitable Arduino boards if slower scrolling speed is acceptable to you. The chipKit UNO32 board is much more capable of producing faster and better scrolling text effect than Arduino boards of around the same price range. This Bluetooth Wireless Serial Port Module is not expensive, easy to work with and quite easily available from online shops. The MAX can see this as valid data and display garbage until the micro-controller gains control. The pull-down resistors prevent these problems.

Thankfully, there is an excellent library that has been specifically written for the MAX which greatly simplifies the sketch — the LedControl library. You will need to download and install the library. Otherwise, there may be some form of 'ghosting' on the displays and may be mistaken to be a hardware issue. You may also want to check out the original LedControl documentation for more detail.

Download the Arduino sketch below which is used for this project. You may amend and enhance the sketch to suit your project. Install the free Bluetooth spp pro Apps onto your Android Smart Phone, power up the display and establish Bluetooth communications between them. Then set up the Bluetooth spp pro Apps buttons for sending messages and commands accordingly.

If you do not have a Bluetooth Wireless Serial Port Module connected, you may test the display by sending messages and commands via the Arduino's Serial Monitor. We will not delve into the details on building the display enclosure here. We used a 2mm thick blue tinted acrylic strip for the display front protective cover which is bent using a self-made strip heater and another black opaque acrylic strip for the back cover. Thinking of building a shorter Scrolling Text Display?

The automatic scrolling of the display content is possible in 4 ways. All features Operating input voltage range from 2. Cycle time and slope time adjustable for each dot separately SPI interface Integrated step-up converter with adjustable output voltage Integrated LDO with 3. Read more Read less.
