Create sprites and icons by drawing individual pixels.
Import photos and edit them within the app, adding and altering colour pixels.
Save the finished art into your files app.

With the app, you can convert your designs into a format readable by the arduino and neopixel library. This allows you to show images on a neopixel matrix.
The pixels in the photo are converted into RGB565 hex code.
If you are using an edp8266 you can also send the RGB565 code to the device via wifi as long as you are using the NeoPixel library and suitable Arduino code
