2. How to develop HM01B0 on Arduino IDE
NOTE: Arduino Software installation and use reference:
- Step 1
Open up the Arduino IDE and go to File->Preferences.
Enter the following URL in the "Additional Boards Manager URLs" field in the dialog that pops up.
Click OK and you will close the dialog.
- Step 2
Go to Tools->Boards->Board Manager in the IDE.
Type "pico" in the search box and select "Add".
Select your development board.
Make sure you are connected to the development board, look at the port number and select it.
NOTE: The port number will be different due to Arduino recognition.
- Step 3
Select HM01B0 USB output example.
Click Download and wait for the download to complete.
- Step 4
Get Processing Script:
Change the port number to the port recognized by Arduino in the script, and run the script in the Processing software.
