# Send Commands to Hackerbot

Connect to the Raspberry Pi via TigerVNC as described in the previous section. Once connected, open a terminal window on the Raspberry Pi and run the following command to initiate a serial connection with the Main Controller Arduino using `miniterm`:

```sh
python3 -m serial.tools.miniterm /dev/ttyACM0 230400 --echo
```

This command opens a serial interface at 230400 baud on `/dev/ttyACM0`, enabling direct communication between the Raspberry Pi 5 and the Hackerbot's Main Controller.

Once connected, you can send commands such as:

* `PING`
* `VERSION`

To test the connection, type `PING` and press **Enter** (on Windows) or **Return** (on macOS). If successful, the response `OK` will appear in the terminal. You can also try sending the `VERSION` command to retrieve firmware version information.
