The funny thing in this project is that it combines two Red LED Matrices as display. You don't need other devices except Arduino to drive it.
This project is build for to counting the shipped with wifi support.
If you are big a fan of pixel art, this project is your type. :)
PS: if you want get more infomation about Open Hardware, follow @HardwareWithYou in twitter. :)
Update: the LED Matrix has an Arduino library in Github.
Step 1: Preparing stuffs
1. Arduino Leonardo (x1)
2. Red LED Matrix (x2)
3. Wifi Shield (x1)
4. Acrylic board as shell (optional)
5. Some jumper wire
6. Simple power circuit (optional)
Red LED Matrix can be controlled by Arduino directly. With Wifi Shield, we can also update our own display's data via wifi network. In addition, acrylic board isn't necessary when you want to make other fancy shells.
To fit the Acrylic board as well as meet the power supply requirement of LED Matrix, we've specially etched a simple and compact power module, which can supply power for Arduino LED Matrix simultaneously.
Besides, you should prepare some jumper wires. As you know, this is a hacking project. :)
Step 2: The schematic circuit diagram of power circuit (optional)
However, it's not necessary in this project if LED Matrix power supply by Arduino Leonadro pin headers.
