2. Upload Firmware
Since we’re going to work in the Stage mode, we must upload the firmware to the board. It will ensure real-time
communication between the board and the computer. Uploading the firmware it is a one-time process. To do so, click
on the Upload Firmware button.
After waiting for a while, the upload success message will appear.
Note: If you are using this board in PictoBlox for the first time, or if this board was previously uploaded with the
Arduino IDE. Then you need to tap Upload Firmware before you can use it.
