Cut the material so that you will get the three pieces as on the picture. The top circle has a radius of 45 cm.

Step 3: Step 3: Insert the LEDS

The first 25 LEDS are for the straight parts. The second 25 LEDS are for the top parts. Use the ordening a shown in the pictures. Connect the two strings together.

Step 4: Step 4: the Code

The code is developed with the Arduino IDE. The library can be dowloaded from Adafruit.

Step 5: Step 5: the Arduino

The Arduino nano is used, but other Arduino are also good.

Green wire is connected to D3

Yellow wire is connected to D2

The LED string is powered directly from the adapter.
