2x2x2 LED CUBE

Hey Guys, here we are using 8 Red LED’s, a Arduino Uno Microcontroller, shift reistors, 6 resistors and 2 NPN transistors to make 2*2*2 LED Cube.

Assembling

The construction of LED CUBE is very simple. At first we have to connect 4 cathodes with each other in each plane of the 4 LED’s. Same thing we have to do with other plane with other 4 LED’s. Finally connect the anodes in each plane respectively.

Connect Resistors and Transistors

We have 4 columns and 2 rows. Each column is connected with 150 ohm resistor and each row is connected with 1K ohm resistor using NPN Transistors.

Connect Shift Resistors and Arduino

Now we have to control 6 outputs (4 columns and 2 rows) so we need 6 wires through Arduino but instead of that we are using a shift resistor (74HC595) IC and we can control 6 outputs using only 3 inputs (Data, Clock and Latch) of shift resistors. Not only 6 outputs, we can control any no of outputs using only 3 pins using shift resistors.
