|
||
It's Node.js + Arduino project to play any midi file.
|
||
>使用node.js把指定的midi文件转为频率和时间，然后串口发送给arduino播放。
|
||
|
||
## Prerequisites
|
||
|
||
1. You need to provide the following environment variables to make it works (the easiest way is to create `.env` file in the project root folder)
|
||
|
||
```
|
||
SERIAL_PORT=<NAME_OF_SERIAL_PORT>
|
||
BOUD_RATE=<BOUD_RATE>
|
||
MIDI_STORAGE_FOLDER=<MIDI_STORAGE_FOLDER>
|
||
```
|
||
|
||
2. Electronics:
|
||
- Arduino Uno
|
||
- Piezo buzzer
|
||
- Wires (optional)
|
||
3. Circuit scheme

## How to run
|
||
|
||
To run the project you have to:
|
||
|
||
1. Upload sketch file from `src/arduino/play.ino` to your Arduino Uno using Arduino IDE or whatever you use for arduino development
|
||
2. Keep Arduino Uno connected to your computer
|
||
3. Run in the terminal:
|
||
|
||
```
|
||
npm install
|
||
node src/node/index.js
|
||
```
|
||
|
||
By default it will start playing files from `midi-storage` (you can change it in the `index.js`)
