How to make a LED scoreboard

Do you require a scoreboard to keep track of the score during your games? This DIY project is perfect for you! Today we will show you how to make a simple LED scoreboard. This LED scoreboard can be used for literally any purpose whether it be during inter-school events or during a friendly game night with the kids. Read more to find out how it is made.


Products needed for this DIY project:

1.      MDF wood

2.      Plexiglass

3.      1 x 4 wood

4.      Diffusers

5.      LED bulbs

6.      LED strip lights

7.      Aurdino

8.      Power source

9.      Wood glue


Let’s get started with our DIY project!


Step 1:

To begin with, take a piece of MDF wood and cut it down so that it’s a rectangle that is 32 inches in length and 18 inches in width using a woodcutter.

Step 2:

Then make the markings using a pencil on the board as follows:

Mark out the center of the board by drawing a straight line. Then draw one rectangle in each section which will be used to display the names of the teams. After that is done make a grid for marking out where you want your LED lights to be. Each section will have 30 LED lights with six lights in each row and five lights in each column. Make all these markings on both sides of the board.

Step 3:

Then you need to start drilling the holes. Initially, you don’t need to drill all the way through. Just make large holes that go halfway through the board where the diffusers will be inserted. Once all these holes are drilled you need to go back and drill smaller holes all the way through in the center of each hole for the LED lights to sit.

Step 4:

Next, you can also cut off the rectangles that you had marked for the team names to be written. Take some plexiglass and cut it down to fit the rectangle that you just cut. Sand both sides to give the plexiglass a translucent look. Then take a trim router with an edge guide, measure the thickness of the plexiglass, and cut off a line of that thickness along all the edges of both the rectangles. Then you simply need to apply some glue and stick the plexiglass in. For the team names, you could use letter stickers so that they can be changed whenever you want. Insert a strip of LED lights behind so that the sign glows.

Step 5:

After this is done, you need to take a piece of 1 x 4 and cut two pieces of 18 inches each and two pieces of 32 inches each to form the frame of the scoreboard. All the angles should be cut at a 45-degree angle so that they fit into each other well. This can be achieved by using a miter saw. Once all the pieces are cut, simply use some glue to stick them into place. You can even use screws to make the frame more secure.

Step 6:

Now it’s time to insert the diffusers. You could 3D print these 60 diffusers or you could buy them from the market. Insert these into the holes that you had made in one of the previous steps. In order to avoid the light from bouncing off from the diffusers, you could wrap the edges of each diffuser with some black tape or even 3D print some black rings to put around the diffusers.

Step 7:

Once the diffusers are in place, let’s work on putting the LED lights in. Taking three columns at a time, put in all the LED lights through the holes and make sure that the structure resembles the one given in the picture below. Since we’re using four different sets of LED lights it’s important to go back and connect them all. Next, you need to connect the LEDs to the Bluetooth Aurdino and to a power source with the help of a voltage converter. Mount all these gadgets to the back of the scoreboard so that they’re all secure.

Step 8:

Now all that’s left to do is to program the lights of the scoreboard to reflect the score that you want. You could create your own code and make a mobile app of your own to control it. Alternatively, you could also download an app called BLE 101 which will connect to the Bluetooth of your scoreboard. This app has controls that can make your LED scoreboard add a point or reduce a point or go back to zero. It’s really simple to use and it’s easily accessible.

Your LED scoreboard is now complete! You can use any color of LED lights as you want and you could even paint the whole body of the scoreboard according to your preferred color. This scoreboard is small enough to be portable but large enough to be seen from a distance. Use it for your next game night or take to school to show your coach. Enjoy your latest creation!
