How to Build Your Own LED Color Organ || Arduino || MSGEQ7

I am showing you how to build a color organ while only using an Arduino Uno, one MSGEQ7 and five external electronic components. I am using three high power led and three MOSFET to visualize the three different frequency bands of the music. Join me for this awesome and educational build.

The video already gives you a lot of details about the build, but I will cover the most important steps again.

Here is a small and easier overview of the components we gonna need:

1x Arduino Uno

1x MSGEQ7

2x 100nF capacitor

1x 10nF capacitor

1x 33pF capacitor

1x 200kΩ(1/4W) resistor or 2x 100kΩ(1/4W) resistor

3x 5Ω(5W) resistor

3x 1kΩ(1/4W) resistor

3x BUZ11 N Channel MOSFET

1x Breadboard

1x Jumper Wires

1x Power supply (5V, 2A)

3x 1W High Power LED (red,green,blue)

If you already have the parts laying around than you can skip to step 4. Otherwise follow step 3 and order your parts

Here is a little part list with example sellers from Ebay and Amazon. I hope it helps you to get your components fast and easy (affiliate links):

Now it's time to get serious. Wire up components on a breadboard is pretty simple and I bet you will get it right after trying a few times. Just follow the schematic

And don't forget to connect the ground wire of your 5V power supply with the ground (GND) of your arduino for potential equalisation. Otherwise the LEDs might do what they want but not what you want.

You have wired up the circuit and it is time for the first test. Just download my code and open it with the Arduino Software (http://arduino.googlecode.com/files/arduino-1.0.5...). Upload the code to your arduino and with the help of some music, the LEDs should light up.

If you think the LEDs change their brightness to slow then feel free to change the delay() time from 30 to 1....30.

You can find the line here:

void loop(){

digitalWrite(resetPin, HIGH);

digitalWrite(resetPin, LOW);

for (int i=0;i<7;i++){

digitalWrite(strobePin, LOW);

delay(30);

Now you can light up awesome cases with your new color organ. I really like to use bottles because it is always a nice suprise for guests when suddenly a bottle lights up.
