For example, to tell the compiler to reserve 11 elements for integer array C, use the declaration −int C[ 12 ]; // C is an array of 12 integers Arrays can be declared to contain values of any non-reference data type. For example, an array of type string can be used to store ...

Note: if you want to read bytes one by one, you can do so with the Serial.read() function. Then you’ll have to convert this(those) byte(s) if needed: int, String, etc.Raspberry Pi Python code#!/usr/bin/env python3 import serial import time if __name__ == '__main__': ...
