Flutter LED controller app


This is the repository for my LED-Control flutter app. It allows you to control the lighting setup of something similar to my longboard lighting project.


This is what the app looks like:

Main Page Device Settings Page Control Panel (disconnected) Control Panel (connected)
Main page settings page disconnected connected

You can add your own device by pressing the ‘+’ Button on the main page and specify the Bluetooth Address and device type in the settings page. Once you stored a device, you can click on it on the main page. This takes you to the control panel. Once connected via the ‘Connect’ Button, all the other Buttons and the slider activate. With these you can control the mode that the light setup is displaying, as well as the brightness of the LEDs.


The app uses the flutter_bluetooth_serial library by edufolly to communicate with an ESP-32 that is driving an LED strip. That may be a setup similar to my longboard lighting project or a simple ESP-32 running this code. The app communicates with the ESP-32 using bluetooth serial. When sending a new command, the app sends an 8-bit integer as a command identifier plus additional integers as data values (e.g. the specific brightness to set). I have provided an example for the ESP-32 code, however you are welcome to modify it or implement your own device types both for the ESP-32 as well as adding your own types to the flutter app.
