### Arduino IDE

You can also use [Arduino IDE](https://www.arduino.cc/en/software)  to modify and upload the sketch.&#x20;

The module code is integrated into the [**OpenCat**](https://github.com/PetoiCamp/OpenCat) project. Uncomment the line **`#define VOICE`**  in the **OpenCat.ino**, as shown in the figure below. Then, use Arduino IDE to upload the sketch to the robot's main board. The robot will work in **Voice mode.** This sketch will allow the robot to behave under voice commands.&#x20;
