How To Make Your Own Led Disco Box
Step 1: Materials Required
Step 2: Preparing the Box
First, we will measure the box and decide accordingly the size of acrylic sheet needed.
I used a square box which was a bit bigger than 6 inch, so I used a 6x6 inch frosted matt acrylic sheet.
I marked on the top of the box where the glass would be and then cut it out.
Then I printed a 6x6 grid and pasted it on a square piece of cardboard just the size of the box so that it is a tight fit
Then I marked where I wanted to place this grid. I decided the depth from top to be 5 cm and used double sided tape to secure it
Now we will cut a foam frame same as the size of the box frame as shown in the picture and will stick it to the cardboard form 3 sides leaving one side open so that the acrylic sheet could slide in, and then spray paint it white.
Step 3: Preparing the Grid
Now we take the grid which we pasted on the cardboard and make a hole at the centre of each square and insert the LEDs. I have only used 25 LEDs out of 50.
Now in order to differentiate the LEDs from each other, we will cut 8 strips of cardboard of length 6.5 inches and of depth 4.5 cm and make slits in all the pieces according to the grid printed and attach it according to the picture
It should look similar to the one in the picture
Step 4: Electronics
This part is the easiest.
The WS2811 led has 3 wires mine has red , white and green colour
So to add a switch we will first we will solder the red wire to the switch and then a jumper wire that will connect to the Arduino (as shown in the picture)
The connections to Arduino is as follows
The red wire is attached to pin 5v
The green wire is attached to pin 5
The white wire Is attached to pin Gnd
Step 5: Coding
Here I have use the FastLed code. But to use it you first have to install the FastLed library
Step 6: Attaching the Glass
Now we will slide the glass in the frame and add super glue to the edges so that it becomes secure .
Make sure that you do not apply to much glue otherwise it will seep through and ruin both the cardboard and the glass.
Step 7: TRY IT !
Connect 4xAA battery or power bank to Arduino, switch it on and enjoy!
