DynamicLedMatrix

DynamicLedMatrix is an IoT student project to dynamically display sensor data on an RGB Matrix and web dashboard. It leverages Arduino- and Adafruit-hardware and a dashboard built with Next.js.

Architecture

The system contains of four main components:

 [ Next.js Webapp ]
         |
         |
[ Firebase Server ]
         |        
         |        
⎡   Arduino Nano   ⎤ <---> [ LED Matrix ]
⎜ ---------------- ⎟
⎜    Temp Sensor   ⎟
⎜ Acclerate Sensor ⎟
⎣    Microphone    ⎦

Arduino Nano: Sends the sensor data to the Firebase Server and communicates with the LED Matrix. The sensor data contains of: Temperature, Noice via microphone and Vibrations via acclerate sensor. All three sensors are build into the microcontroller.

LED Matrix: Displays the sensor data in a funny way. For example: If the microcontroller detects loud noice in the sourround, there will be presented a funny message on the LED Matrix with a cute character complaining.

Firebase Server: Stores the data temperature, noice and vibration data via the Realtime Database.

Next.js Webapp: Allows to see an curve of the last temperature values. Aswell there is a bar chart showing the noice and vibration data.
