LEDs-Music-Visualizer

---

Intro

LEDs Music Visualizer system consists of Arduino and Seven Band Graphic Equalizer - MSGEQ7 which is able to illustrates the audio spectrum from the input sound through the LEDs strips.

Ingredients

• Arduino UNO
• MSGEQ7
• 5V Power Supply (≥ 4A)
• Addressable LEDs (60LEDs)

Procedures

1. Follow the circuit schematic
2. The values of capacitors and resistors are based on J Skoba diagram for MSGEQ7
3. Connect Arduino to the computer with USB cable
4. Adjust the pins values, in this case, A0 = audio, D2 = Strobe, D3 = reset and LED_PIN = 6
5. Upload the code
6. Voilà!

**ATTENTION**: If you smelt something's burned, it would probably too late! Throw everything away, realize you just waste ~20$, rethink about your life decisions, then buy the whole stuffs and start all over again.

Note: Add 22k resistor between the Audio In (one that goes to MSGEQ7) and the capacitor (10nF)
