ESP8266_MQTT_Speaker

Hacksmith Vlog #Null

Simple MQTT Speaker utilizing "dfplayer mini" to play preloaded sounds.

The code has been simplified from the original and is meant to be used as a helper for your own original work. Most functionality is still within the project.

Required Components

1 - ESP8266 (Your choice but project used D1 Mini)
2 - dfplayer mini
3 - 4ohm or 8ohm speaker (4 watt MAX)
4 - SD Card (Keep this under 32GB)

Required Infrastructure

1 - MQTT - Self Hosted (I would chose this. Use it with a raspberry pie or VM. Google it for more information)
2 - MQTT - Cloud Hosted (Something like this)

Required Arduino Capable Board Libraries

1 - ESP8266 (Here is how to install it)

Required Module Libraries

1 - Arduino.h
2 - ESP8266WiFi.h (Comes with ESP8266 Board Library)
3 - SoftwareSerial.h
4 - PubSubClient.h (MQTT)
5 - DFrobotDFPlayerMini.h (For the audio Player)
6 - StringSplitter.h

MQTT command for Playing file

Topic : Hacksmith/Speaker/announce_speaker/1/announcement
Msg : 30^01^002
Description : This will > Set Volume to 30 > Go into folder #1 > Play Audio clip labeled 001

MQTT command for Changing Volume

Topic : Hacksmith/Speaker/announce_speaker/1/volume
Msg : 0 - 30
Description : Sets the volume from 0(0%) to 30(100%)

MQTT command for Pausing Audio Playback

Topic : Hacksmith/Speaker/announce_speaker/1/control
Msg : pause
Description : Pauses current audio playback

This is not the same as having a PA (although it can be used as one for pre-baked msessages). This is for simple everyday announcements like doorbells, lunchtimes, deliveries, etc.
