Just like ingredients for cooking, before starting the project, you must prepare some stuff. All you need is listed below:
1. Arduino Leonardo
2. Red LED Matrix
3. Wifi Shield
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. :)
