Serial.print fails

[DhruvaG2000]

The wrapper for Serial.print(val >> i & 1, BIN); and Serial.print(i, HEX); is probably missing which causes build failures.

Refer: https://www.arduino.cc/reference/en/language/functions/communication/serial/print/

Serial.print(78, BIN) gives "1001110" Serial.print(78, OCT) gives "116" Serial.print(78, DEC) gives "78" Serial.print(78, HEX) gives "4E"

Even more missing features:

Also need to add #include <zephyrSerial.h> to Arduino.h or else it doesn't find Serial

[soburi]

@DhruvaG2000 This issue may solve with #64. Could you confirm it?

[DhruvaG2000]

Yes now we need to clean up the samples/hello_arduino. we can delete the #include "zephyrSerial.h" line and also cleanup a bit. I will send a PR for this cleanup
