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.- CD 4020
- NE 555
- 10uf
- 33K
- 27 white LEDs
