I want to implement a code that runs the motor when the QR code number I read using the QR reader is 210305***, but I don’t know how to do it, I need some help
I’m using this Barcode Module.

#define CW 1900
#define STOP 1450
#define CCW 1000

OnScanFinished();
}
// If not, continue normally
else {
// If bit position not in 2, it's uppercase words
OnKeyScanned(i > 2, buf, buf[i]);
}
return;
