Step 7: The controller

The circuits controlling the led cube is described in the attached schematic image.

The RS-232 interface is optional. and can be omitted. That is IC2 and all the components connected to it. Future firmwares will enable PC communication..

Start by laying out all the components on you circuit board in a layout that enable all the components to connect with a minimal amount of wires. If everything fits, solder the circuit.

I won't give any more instructions on this, as the circuit probably will look very different from cube to cube, depending on the size of the circuit board etc..

Information on how to wire the cube to the controller circuit is in the next step.
