Kira’s Final Project-Music Light


Project Description:

The Interactive Music Light is an innovative DIY project that combines sound sensing technology with lighting effects to create a dynamic lighting experience that changes with music. Utilizing an Arduino controller and an Electret Microphone Amplifier Module MAX4466, this device captures ambient sound and adjusts the brightness of an LED light in response to the sound intensity. This unique design not only provides a dynamic visual display but also adds an interactive element to any space.

Key Features:

Sound Activation: The device captures audio signals through its built-in microphone module, responding in real-time to music and sounds in the environment.

Brightness Adjustment: The LED light’s brightness varies in accordance with the captured sound intensity, creating light effects that synchronize with the music rhythm.

Arduino Powered: Leveraging the flexibility and user-friendliness of Arduino, the system’s design is both simple and easy to implement.

3D Printed Enclosure: The device comes with a custom 3D printed treble clef enclosure, adding an artistic aesthetic and personalized style.


The Interactive Music Light is perfect for home parties, cafes, studios, or any setting that requires a dynamic atmosphere. It’s not just an elegant lighting solution but also an educational tool that sparks interest in the convergence of technology and art.

  3. LED Strip.
  4. Conductor.

Circuit Planning


Renew on 11/28

In order to save time and simplify the build process, I tried to find some treble symbols online that fit my requirements, and to my surprise I did find a fitting that fit the criteria perfectly, all I had to do was to disassemble it and fit it into the strip of lights that I had entered the code for and I was good to go.

To further research how to best accomplish my project, I bought a similar music light and took it apart to study its circuit board and how it was assembled. Truth be told, it didn’t inspire me much, and I still feel like sticking to the original plan.

Kira’s Final Project Planning

Material Preparation:
Photoresistor: used to detect the ambient light intensity.
Color LED: used to display different colors.
Microcontroller (e.g. Arduino): used to control the LED and read the value of the photoresistor.
Resistor: used to limit the current and protect the LED and the photoresistor.
Breadboard and/or soldering tool: used to build the circuit.
Wires: to connect the parts of the circuit.
Power source: can be a battery or a stand.
Sensors (optional): such as temperature and humidity sensors for weather-related functions.
Programming cable: connects the microcontroller to the computer.

Circuit diagram design:
Connect the photoresistor to one of the analog inputs of the Arduino.
Connect each of the RGB LED color pins (red, green, blue) to a digital output of the Arduino through appropriate resistors.
If needed, connect the sensor other to the Arduino.
Connect the power supply:
Ensure that the microcontroller has a stable power supply.
Choose a battery or adapter as needed.
Consider additional features:
To control the color according to time or weather changes, an Ethernet module (e.g. ESP8266) may be needed to get the time or data.
Write and upload code:
Write code to read the value of the photoresistor and control the brightness of the LED or switch it on/off based on that value.
Write code to change the LED color, either based on time or weather data obtained from the network.

Zhiwen(Kira) Fu’s Final Concepts

1. plant grow light controller:

Use an Arduino to control a set of LED grow lights to automatically adjust the light intensity according to different times of the day, mimicking the natural photoperiod and helping indoor plants grow.

2. Holiday countdown device:

Make a device that shows how many days are left until a specific holiday. It displays numbers and can play a holiday song or display a special message on the day of the holiday.

3. smart night light:

Create a nightlight that automatically turns on or off using a photoresistor. The nightlight will automatically turn on when the environment becomes dark and turn off when the environment becomes bright. Color LEDs can be further added to display different colors depending on the time of day or weather.

Zhiwen(Kira)-Halloween Project

I chose to make a glowing wing because I’ve always wanted to have a pair of bat wings, it would make me look cool!

I sketched it out first and plan to follow the framework.

I used two sizes of wire for the outer rim frame and the inner support structure.

Wrap the metal part with black floss (I wanted to create a darker look)

Try using little ways to make the wings stand up so they look more three dimensional.

Test the wings to see if they are solid enough.

Test led strip light

Install the led strip and wrap the exposed excess again with black fleece.

Final test, looks good but it’s easy to have an accident (for example, later on my light strip broke off partially causing poor contact and only showing green)

Had a great time this Halloween, thanks to the course.

Kira’s Halloween Ideas

Arduino board
6 light strips
6 x 220Ω resistors
Power supply
Dupont wire or other connecting wire
Black fabric
Steel skeleton


If everything is connected correctly and there are no errors in the code, each strip should light up one after the other when I power up the Arduino.


To do:

Using wire to make a frame
Cover wire with black cloth
Attach the LED lights

Plush NightLight Proposals from Kira

Handle a cute teddy bear doll!

There are three sources of inspiration for me:

1: My first fabric doll from my childhood. Legend has it that every child’s bedside doll accompanies them to dreamland and protects them from nightmares.

2: Mr. Black, who accompanied me when I was the loneliest in my high school years. He came from the miniature world and had no hands but only a pair of long and skinny legs, and he was my favorite friend, and I would take him with me wherever I went, but once I lost him when I took him out of the house, and I was sad for a long time.

3: Still in my happiest childhood, this was my favorite creature to observe-a caterpillar (it didn’t look like much), which meant well, and even though he doesn’t look that great now, he’s going to turn into a beautiful butterfly eventually, which sounds great.

I finally decided on a teddy bear ragdoll because I haven’t been sleeping very well lately and I thought he would help me the most, so I started choosing fabrics and made him a lace choker.

The final product is a little small but looks ok.

Ipod Touch Teardown

First Breakdown of iPod touch


1. I need to open the front panel first, you need to use a hair dryer for this step because the front panel is glued.

2. Then we can see the digitizer glass layers, there are some cool multilayer layers in there which make up the display. 

3. After that there are a lot of tiny screws that need to be unscrewed, so be careful, they can get lost if you’re not careful.

4. Once all the screws have been unscrewed, we can take out the mid chassis. 

5. Then there is the main board and the battery, the main board is connected to a lot of small accessories: camera, camera cap, volume buttons cable, ear phone jack….

6. be careful when removing the battery, because it is soft and I always worry that it will explode.

7. when everything is off, we can take off the rubber frame. 

8. When there is only one piece of housing chassis left, the disassembly is finished!
