4x4x4 LED-cube Based Arduino and Flower Protoboard

Because of I often use protoboards to test out if a new idea works in practice. I do not use breadboards anymore because I pretty much use only smd parts and I hate the connection problems and high parasitics that breadboards have.

So the Flower ProtoBoard was born.  You can solder SMT component. Include 0402, 0603, 0805，SOT-23 and so on. Especially the issue with the longer solder "wires".

At this LED Cube project you will see the ProtoBard point-to-point wiring is very clear.




The Flower ProtoBoard from ElecFreaks is receiving  request sample on December 2011.

Note: the demo code LEDPin and LayerPin need change your Arduino IO. Here we define as below:

// Initalize our LED columns (positive)
int LEDPin[] = {6,5,24,26,28,30,32,34,36,38,40,42,44,46,48,50};
// Initalize the LED layers (ground)
int LayerPin[] = {10,11,12,13};

Draw on the bottle a grid with the lines 10.16 mm apart. (Because you will fix the led onto protoboard at the end, so you must fit for the protoboard holes distance.

Our Flower protoboard hole distance is 2.54mm, 4×2.54mm=10.16mm ) Draw 4 lines horizontally and 4 lines vertically. Then use tweezer or other sharp tools drill holes.

As the picture shown, the longer pin is the cathode. Bending the legs accord with the arrow.

Each cathode of LED  is soldered  together. Make sure that you don’t solder an anode to an cathode.

This step is a little difficult. You’d better  place the LED as the direction shown on the picture then solder each layer together(solder the anode of different layer together. We call it column. Each column need a IO to control.).  In this way, you will easy to solder the column in the middle.

Each anode is a column. A B C D is the cathode of each layer. So we need 16+4=20 IOs to control the 4X4X4 LED cube.

You can easy to wire on our Flower protoboard. Red square in the picture is 1k 0603 resistors.

Now you have completed the entire  process. Next you need to put it into the freaduino, and download the code.Before you start to paly it. We should briefly explain how does the LED cube work. The schematic of LED cube is very simple.

The LED cube 4x4x4 has a total of 16 transistors are used to switch on the Led columns and then another total of 4 lines to switch on or off the ground layer. So a total of 16+4 = 20 lines are needed to make the LED cube 4x4x4 work. It is important that the 4 ground layers are switched bwteen them to stwich one layer at a time and the swicthe the desired led’s on the partucular layer.

I believe you already have enough  understanding of  4X4X4 LED cube.

Now please enjoy it.
