DIY Music Reactive Phone Mood Light110

Create an immersive musical experience with this interactive phone mood light that dances to the rhythm of your favorite tunes. This DIY project transforms your smartphone into a vibrant light display, enhancing your music listening sessions with a captivating visual element.

Materials:* Cardboard box
* X-Acto knife or craft knife
* Ruler or measuring tape
* Pencil
* Transparent plastic or tracing paper
* LED strip lights (any color, length depends on box size)
* Arduino Nano or compatible microcontroller
* Wires
* Breadboard (optional)
* Smartphone with music player
* Audio cable (optional)

Instructions:

1. Cut the Cardboard Box

* Measure and mark a rectangular opening on one side of the cardboard box, large enough to fit your smartphone.
* Carefully cut out the opening using an X-Acto knife or craft knife.

2. Create the Transparent Window

* Trace the opening onto transparent plastic or tracing paper.
* Cut the plastic to match the size of the opening.

3. Attach the LED Strip Lights

* Adhere the LED strip lights around the inside edge of the cardboard box, just inside the opening.
* Make sure the LED lights are facing outwards, towards the transparent window.

4. Wire the Circuit

* Connect the positive (+) terminal of the LED strip lights to the 5V pin on the Arduino Nano.
* Connect the negative (-) terminal to the GND pin.
* If using a breadboard, insert the Arduino and connect the LED strip wires accordingly.

5. Connect the Audio Cable (Optional)

* For a more responsive light display, connect an audio cable from your smartphone's headphone jack to the Arduino's analog input pin (e.g., A0).

6. Program the Arduino

* Open the Arduino IDE and upload the following code:
```c++
#include
// LED Strip Configuration
#define NUM_LEDS 60 // Adjust this value to match the number of LEDs used
#define LED_PIN 5 // Digital pin connected to LED strip
#define COLOR_ORDER GRB // Color order of your LED strip (usually GRB or RGB)
// Audio Input Configuration
#define AUDIO_PIN A0 // Analog pin connected to audio cable (optional)
// Create an LED Strip object
CRGB leds[NUM_LEDS];
void setup() {
// Initialize FastLED library
(leds, NUM_LEDS, LED_PIN);
}
void loop() {
// Read audio input (optional)
int audioLevel = analogRead(AUDIO_PIN);
// Set LED brightness
for (int i = 0; i < NUM_LEDS; i++) {
leds[i].setBrightness(audioLevel * 16);
}
// Apply color effects
// Feel free to adjust or add your own color effects here
// Display the LEDs
();
}
```

7. Assemble the Light

* Insert your smartphone into the opening on the cardboard box.
* Place the transparent window over the opening to cover the LED lights.
* Connect the Arduino to the LED strip and audio cable (if used).
