Hello friends. Today we are going to make a 3x3x3 LED cube project. This project is based on the arduino. Now let's do it.
Requirements :-
27 LED's
9 resistors - 1K ohm each
A general purpose PCB board
Arduino uno board
Soldering gun
Wire cutter
Connecting Wires
Now let's start making.
Follow the steps given below:-
1. First we have to connect LED's in a proper format.
2. Take a thick cardshit paper. Draw a 3x3 square pattern on it. As shown below.
3. This will acts as a base for your LED model.
4. Now place all 9 LED's in each slot.
5. Then connect the negative (i.e. shorter) terminal of each LED to the next LED as shown. And keep the positive terminal as it is.
6. Here we are connecting negative terminals of all LED's together. After soldering, take out the first layer which will looks like as shown.
7. Form such three layers. Now place one layer on the top of other such that all 9 positive terminals of upper layer will just touch the 9 positive terminals of the layer below. And solder them.
8. Now you will see that there are total 9 columns and 3 rows.
9. Connect the cube on PCB.
10. Give numbering as shown.
11. Now connect wires to each columns and rows. So there will be total 9+3=12 wires.
12. Connect 1K resistor to each column wire. This will form our setup.
13. Now let's focus on the coding.
The code is given as below.
14. Now connect the columns 1 to 9 to the pins of arduino from 1 to 9.
15. Connect three rows to pins 13,12 and 11 respectively.
16. Carefully do the connections. Avoid any mismatch.
17. Now burn the code into the arduino. And you can see different patterns are generating on the LED cube.
Hope you like the project.
