First, install the Arduino IDE. Once it is installed, find the folder where you saved the library and load it into your computer. Then, open the Arduino IDE and click on the options button in the upper left hand corner of the screen. In the options window that opens, click on the Sketchbook tab, then click on the Examples button in the top right hand corner of the window. Double-click on the LED strip example to open it in a new window.
Next, if you have not already done so, connect your Arduino to your computer using a USB cable. Once your Arduino is connected, select it from your computer's list of devices. Next, open the sketch that accompanies the LED strip example and confirm that everything is set up correctly by clicking on the check mark next to the word "Arduino." Then, click on the write button to begin uploading your code to your Arduino.
When your code has been uploaded successfully, you will see a message
