Introduction: Arduino Light Show
Step 1: Parts
Here are the parts you will need to have this accomplished, where to find them, and what you will need out of them:
-Arduino UNO, MEGA, or DUO
(Recommend MEGA) Link
-Radio Shack Sidekick Basic Kit Level one for Arduino
From it you will need:
-Breadboard (circuit board)
-ALL Long wires and some short wires
-20 2- leg LED lights
Link
-Computer with Arduino Software and USB Cable
Arduino Software
Step 2: Step 2: Insert LED on Outer Part
You will now start by taking the LED lights and separating them by color (10 of each).
Before we advance, I want to inform you of the difference of the positive and negative on the LED. The longer of the two is positive.
Start by placing 5 LEDs of the same color on one of the ends of the board with the + and - signs on it. Be sure to remember to put the longer in the positive. Then take another color and place 5 the same way on the other side of the board. When you are done, it should look like the picture shown
Step 3: Step 3: Insert Middle LEDs
Now one of the more difficult parts: Adding the LED in the center.
In the middle, Each numerical row is one circuit. Each LED will take up two numerical rows. It will be hard but look at the pictures for help with inserting them. Make sure to remember to face the positives in the same direction and label the pos and neg ends.
Step 4: Step 4: Insert Negative Wires
Please look at the different figures of the breadboard to figure out how the wires go. Green wire is long and the rest are short
Step 5: Step 5: Insert Positive Wires
Pay CLOSE attention to the positive wire placement. They will be overlapping the LEDs and others but just pay attention where they plug in. They will all be BLUE but they may differ from your choice. Use the rest of your long wires and finish off with the small wires
Step 6: Step 6: Program Arduino
Now you will need to plug your Arduino into the USB cable coming from your computer. You will need one to communicate with your Arduino for any project. Message me if you need help finding one.
You need to open the Arduino program and make sure it is blank. You will want to click the link below to copy and paste the code:
CLICK HERE TO GO TO THE CODE PAGE DOWNLOAD
Download instructions:
1) Download the file.
2) Hit SAVE if prompted
3) Open the folder with the Arduino app in it and open your downloads folder in another window
4) Open the examples folder in Arduino folder
5) Drag the folder you downloaded into that folder
6) Right click it and click UNZIP
7) Now hit the back button to go back to the main screen and double click the Arduino app
8) After it opens, click File-Examples-sketch_dec26a
9) Plug Arduino in and hit the right arrow at the top known as UPLOAD
Step 7: Step 7: Test It Out!
Press the little reset button and watch your show dance the night away! If there is a problem that you cannot figure out, message me and I'll be glad to help

dont you need any resistor? becouse i don't want my leds to burn out

I have an Arduino Uno Rev 3 will it still work with the same code?

I only have an Arduino Duemilanove - it has 0 - 13 digital pins - will this still work? I should think so but just wanted to check.
Thanks!

Yes. I used my analog pins too. Just use the numbers corresponding to the analog pins in the code

do I have to use a certain color wire? I see you are using two yellows, blues, reds, and one green. I don't have enough blue wires. Could I use another color wire?

Yes you can. It doesn't matter what the color is, only whether the connections are correct. Hope you enjoy!!

Cool USB cable! Where can i get it???

I got mine from amazon. It's very cheap like about $6. Have fun with the project!
