How to make a simple L.E.D cube

LED cube is very famous because of its beauty. Here is the circuit diagram for very simple LED cube. In this circuit we used 27 white LEDs. The 4020 IC is a Simple 14 stage binary counter and we have used here 9 outputs. Each output drives 3 white LEDs in series and we have omitted a dropper resistor as the chip can

only deliver a maximum of 15mA per output. The 4020 produces 512 different patterns, before the sequence repeats. So you have to build the project to see the effects it produces on the 3D cube.im pretty sure u might be like this.
