Step 12: Make the Circuit Step 06

Solder the 3x NPN Transistor shown in the picture

Step 13: Add LED Cube to Circuit

Put the 9 LED pins into red coloured circle holes and solder.

Step 14: Add LED Cube to Circuit Video

Step 15: Connect 3x3x3 LED Cube to Arduino

Cut same size 16 wires and solder it picture shown below (I use ribbon wire)

Pins go to Arduino

A – Negative (0v)

B – Arduino pin 13

C – LED Cube level 1 (light green wire)

D – Arduino pin 12

E – LED Cube level 2 (light green wire)

F – Arduino pin 11

G – LED Cube level 3 (light green wire)

H – Arduino pin 10

I – Arduino pin 09

J – Arduino pin 08

K – Arduino pin 07

L – Arduino pin 06

M – Arduino pin 05

N – Arduino pin 04

O – Arduino pin 03

P – Arduino pin 02

Step 16: Upload Code to Arduino

This is simple code. If you go through it you can

understand how I am going to make design.
