This cube is different from others for many reasons:
1. It connects directly to your Arduino.
2. It uses few components, so its relatively inexpensive.
3. Runs on code that's easy to write. or you can use the ones provided.
4. Everything can be bought at your local Radio Shack
- 64 diffused LED Lights (it cost a lot less to order 1000 off ebay for around $20) (Also i used 3mm LEDs, but 5mm or 8mm would work to)
- 16 220 resistors
- 4 22k resistors
- 4 NPN type Transistors
- 1-2 Perfboard (The kind with the little copper circles) (you only need one if you are good at compacting your soldering unlike me....)
- 1 Arduino (I went ahead and bought a MEGA so there's room to expand fro future projects, however UNO has just enough i/o ports)
- Insulated 22 gauge Wire
- some craft wire
the Arduino was the most expensive part at around $60 For MEGA and i think a UNO is around $30.
So if you already have a Arduino the cost is brought down to $40.
- Basic electronics and soldering
- Be capable of following directions
