Most of them can be ordered cheaper directly in China. It's just a give an short impression of the hardware. Most of them can be ordered cheaper directly in China. It's just a give an short impression of the hardware.
## Getting Started ## Getting Started
I recommend Microsoft's [Visual Studio Code](https://code.visualstudio.com/) alongside with [Platformio Plugin](https://platformio.org/install/ide?install=vscode.) My project in Github contains platformio.ini, so libararies used should be fetched automatically. Please note: If you use another ESP32-develboard (Lolin32) you have to change "env:" in platformio.ini to the corresponding value. Documentation can be found [here](https://docs.platformio.org/en/latest/projectconf.html). After that it might be necessary to adjust the names of the GPIO-pins in the upper #define-section of my code.

Optionally, GPIO 17 can be used to drive an NPN-transistor (BC337-40) that pulls a p-channel MOSFET (IRF9520) to GND in order to switch off current. Transistor-current is described [here](https://dl6gl.de/schalten-mit-transistoren): Just have a look at Abb. 4.

## Interacting with Tonuino-ESP32
Todo...
## Prerequisites
* For debugging-purposes serialDebug can be set (before compiling) to ERROR, NOTICE, INFO or DEBUG.
* Make decision, if MQTT should be enabled (enableMqtt)
* If yes, set the IP of the MQTT-server and check the MQTT-topics (states and commands)
* In setup() RFID-cards can be statically linked to an action/file.
* Compile and upload the sketch
## Starting Tonuino-ESP32 first time
After pluggin in it takes a few seconds until neopixel indicates that uC is ready by four (slow) rotating LEDs. If uC was not able to connect to WiFi, an access-point (named Tonuino) is opened and after connecting this WiFi, a [configuration-Interface](http://192.168.4.1) is available. Enter WiFI-credentials, save them and restart the uC. Then reconnect to your "regular" WiFi. Place to favourite RFID-tag next to the RFID-reader and the music should start to play.
## Interacting with Tonuino
### Playmodes
It's not just simply playing music; different playmodes are supported:
* single track
* single track (loop)
* audiobook (single file or playlist; last play-position is saved when next track is played, pause, previous, next is pressed)
* audiobook (loop)
* Folder/playlist (alph. sorted)
* Folder/playlist (random order)
* Folder/playlist (alph. sorted) as loop
* Folder/playlist (random order) as loop
