Important Notes for Students

If the board is not detected, press the BOOT button (on back) while connecting USB. This forces the device into bootloader mode for initial setup and recognition.

The code runs ON the board, not on the computer. Your PC is only used to write and upload the program; all computation and interaction happen directly on the embedded hardware.

Once code is uploaded, you can disconnect USB and the board runs independently. Power the board with a battery or external supply to use it as a standalone device.
