Get Slack Status on Dot Matrix LED Display

Brief Description:

This is an ESP8266 project on the Arduino platform, where it retrieves a user profile status from Slack.

Sometimes your colleague with you in the same office didn't recognize your status while you are on a meeting/call or focusing on some tasks. So using this project you will be able to show everyone your status at any time by setting your status on Slack and this little hardware will get it shown on the Led-Matrix display 😁

Arduino Libraries:

• Adafruit GFX Library
• ArduinoJson
• AsyncTCP_SSL
• AsyncWebConfig
• ESP8266WiFi
• ESP8266HTTPClient
• WiFiClientSecure
• TaskScheduler
• ESPAsyncWebServer
• Max72xxPanel

• ESP8266 Board
• Dotmatrix LED Display 8x32 max7219
• Wires and connectors
• 3.3v Power source

Create a Slack app and follow the instructions in the screenshots to get the App token and your user ID, write down those data and keep them in a safe place, you will use them at a later step.

The JSON code provided below will be used in step 4 during the app creation in order to determine the app scope

You can validate your token and user ID on Slack API Documentation Page

{
  "display_information": {
    "name": "GetUserStatus"
  },
  "features": {
    "bot_user": {
      "display_name": "GetUserStatus",
      "always_online": false
    }
  },
  "oauth_config": {
    "scopes": {
      "bot": [
        "users.profile:read"
      ]
    }
  },
  "settings": {
    "org_deploy_enabled": false,
    "socket_mode_enabled": false,
    "token_rotation_enabled": false
  }
}
