### Configuring the Programmable Button on the Opta™

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

***Important: It is not possible to program the Opta™ while it is being powered with the power pins. You would need to disconnect the power supply, upload the program and then connect the power again.***

### Using Opta™ PLC's Inputs

Opta™ has 8 input pins that can be programmed to be used as analog or digital. The mapping between the marking on the Opta™ physical terminals (I1 to I8) and their definition in the core can be found below:
