# Emotion-Detection-in-Music
The aim is to build a model which will take an audio file as input which will then predict one out 5 classes namely - happy , sad , angry , peaceful , love.
## Data Collection
The dataset consists 600 songs belonging 5 classes (happy,sad , angry , peaceful , love) . Each class has 120 songs .
## Preprocessing
### Feature Extraction
Mel-Frequency Cepstral Coefficients (MFCCs) are coefficients that collectively make up an MFC. They are derived from a type of cepstral representation of the audio clip (a nonlinear "spectrum-of-a-spectrum").
### Label Encoding
Label Encoding is used when we have labels in words like 'happy', 'sad', 'angry' etc.
It converts these labels into integer values so that machine learning algorithms can understand them.
## Model Training
A convolutional neural network was built using keras library for training purpose . The model had two Convolution layers followed by two max pooling layers . Finally it had two dense layers at last .
The model was trained on 80% data i.e 480 songs per class whereas validation was done on remaining 20% data i.e 120 songs per class .
### Training Accuracy vs Validation Accuracy
### Loss vs Validation Loss
### Testing
The model gave around 95% accuracy while testing .

## RFID Badge for Wearables Capstone project
This capstone project is designed by Joe Blow (Joe Chen). The goal is design an RFID badge for wearables device like bracelet or watch.
The first step I did was create this github page so I can keep track my progress.
In this capstone project I will be using RFID technology instead bluetooth because RFID technology uses less power consumption than Bluetooth technology does.
This project will consist three parts:
* Hardware part
* Software part
* Web service part
For hardware part I planed use Atmega328P microcontroller since it has been widely used before in Arduino Uno board which means there should be plenty tutorials available online if I got stucked somewhere along development process.
For software part I planed use Python language since it has been widely used before in web development field which means there should be plenty libraries available online if I got stucked somewhere along development process.
For web service part I planed use Node.js since it has been widely used before in web development field which means there should be plenty libraries available online if I got stucked somewhere along development process.
At first stage I planed design simple prototype circuit board using breadboard then move onto designing PCB later after everything works fine.
Here's my progress:
### Step One:
I bought all necessary components including microcontroller Atmega328P chip breadboard jumper wires etc.
I soldered Atmega328P chip onto breadboard then connected various components like resistors capacitors etc onto breadboard according schematic diagram provided by Arduino website.
I uploaded Arduino IDE sketch code onto Atmega328P chip using USB cable then tested if everything works fine.
It works perfectly! So far so good!
### Step Two:
I started designing PCB layout using KiCAD software package.
After several hours spent designing PCB layout finally finished first draft version which looks pretty good!
Next step would be ordering PCB prototype boards from manufacturer such as JLCPCB or Seeed Studio etc once they arrive here at home lab station then soldering all necessary components onto PCB boards accordingly schematic diagram provided earlier earlier earlier.
Once everything soldered correctly onto PCB boards next step would be uploading Arduino IDE sketch code onto Atmega328P chips again using USB cable then testing if everything still works fine after being transferred over from breadboard setup earlier earlier earlier.
If everything still works fine after transferring over from breadboard setup earlier earlier earlier then congratulations! You've successfully completed step two!
However if something doesn't work properly after transferring over from breadboard setup earlier earlier earlier then don't panic! Just double check connections between various components according schematic diagram provided earlier earlier earlier again carefully until problem identified resolved fixed fixed fixed.
Now let's move onto next stage shall we?
### Step Three:
After receiving PCB prototype boards from manufacturer such as JLCPCB or Seeed Studio etc finally arrived here at home lab station ready for assembly.
First thing first let me explain what exactly am trying accomplish here shall we?
Basically what Im trying accomplish here is creating custom designed RFID badge wearable device capable communicating wirelessly via NFC protocol between itself other nearby devices such smartphones tablets laptops etc without requiring any additional cables wires connectors whatsoever!
In order achieve desired goal stated above firstly need develop custom designed circuit board capable hosting microcontroller Atmega328P chip alongside necessary supporting components such resistors capacitors transistors diodes etc according schematic diagram provided previously previously previously.
Once custom designed circuit board developed successfully next step would involve assembling various components soldering them securely onto corresponding pads holes drilled specifically intended purpose upon aforementioned custom designed circuit board accordingly schematic diagram provided previously previously previously once again once again once again until final product resembles exact replica original design intended purpose initially envisioned originally envisioned originally envisioned originally envisioned originally envisioned originally envisioned originally envisioned originally envisioned originally envisioned originally envisioned originally envisioned originally envisioned originally envisioned originally.
Now lets move onto actual assembly process shall we?
First thing first need acquire necessary materials required assemble aforementioned custom designed circuit board mentioned above mentioned above mentioned above mentioned above mentioned above mentioned above mentioned above mentioned above mentioned above mentioned above mentioned above mentioned above mentioned above:
