 ### Configuring the Programmable Button on the Opta™
 
-Opta™ has a programmable button, shown in the image below and identified as USER. It can be programmed using the Arduino IDE to fit your needs. To show how simple it is to use, let's create a sketch and program the button as a trigger to modify the status of the STATUS LEDs.

-The button is defined in the core as `BTN_USER`: 'HIGH' as default (not pressed),  and 'LOW' when pressed. The new sketch will turn on the STATUS LEDs one by one when the button is pressed and then start over when all the lights have been turned on. Below you can find the entire sketch, where a simple [Switch (case) Statement](https://www.arduino.cc/reference/en/language/structure/control-structure/switchcase/) is used, and an image highlighting where the USER button is located on the device.
