To be able to communicate with blokdots, the Arduino board needs to be flashed with Firmata, a protocol that allows it to communicate with your computer. Once you open blokdots and plug in your Arduino, blokdots flashes the board with the Firmata automatically. However, in case you get an error message that Firmata cannot be uploaded you can follow these steps to troubleshoot it:

Open Arduino IDE → File → Examples → Firmata → StandardFirmata → Click on the Arrow icon to upload Firmata. Once the sketch is compiled, you will get a notification message that Firmata has been successfully uploaded.

If your board does not appear in the Arduino application Port menu and you get a “Board not connected” message in your blokdots application, please follow these troubleshooting steps.
