1. Open Arduino IDE, and open the [client.ino](https://github.com/OpenInterpreter/01/blob/main/software/source/clients/esp32/src/client/client.ino) file
Finally, to flash the .ino to the board, connect the board to the USB port, select the port from the dropdown on the IDE, then select the M5Atom board (or M5Stack-ATOM if you have that). Click on upload to flash the board.
You don't need anything, PlatformIO will install everything for you, dependencies, tool chains, etc.
Please install first [PlatformIO](http://platformio.org/) open source ecosystem for IoT development compatible with **Arduino** IDE and its command line tools (Windows, MacOs and Linux), and then enter to the firmware directory:
```bash
cd software/source/clients/esp32/src/client/
```
And build and upload the firmware with a simple command:
The board needs to connect to WiFi. Once you flash, connect to the ESP32 WiFi portal "01-Light" which will get WiFi details. Once it connects, it will ask you to enter 01OS server address. Once its able to connect, you can use the device.
