Connect your phone to Arduino via bluetooth and control the Neopixel LED rings remotely. The colors you choose on the color scale are instantly sent to Neopixel LEDs and a visual feast is created.
By activating the random colors option, you can observe automatic color changes.
You can adjust the brightness of Neopixel LEDs at any level.
You can set 3 different profile buttons with the color and brightness you want, to do this, first tap on the color you want, change the brightness setting, and finally press and hold the profile button you want, give the profile a name and save your profile. You can use your saved profiles every time you run the application.
The Arduino program I created will automatically detect the number of LEDs connected to the Arduino board.
