serial print arduino code example

Example 1: arduino format specifiers

* %d = signed integer               %f = floating point number  
 * %s = string                     %.1f = float to 1 decimal place
 * %c = character                  %.3f = float to 3 decimal places
 * %e = scientific notation          %g = shortest representation of %e or %f                
 * %u = unsigned integer             %o = unsigned octal
 * %x = unsigned hex (lowercase)     %X = unsigned hex (uppercase)
 * %hd = short int                  %ld = long int
 * %lld = long long int

Example 2: arduino print array

for(int i = 0; i < size_of_myArray; i++)
{
  Serial.println(myArray[i]);
}

Example 3: arduino serial write

/*
Writes binary data to the serial port. This data is sent as a byte or series of bytes; to send the characters representing the digits of a number use the print() function instead.

Syntax
Serial.write(val)
Serial.write(str)
Serial.write(buf, len)

Parameters
Serial: serial port object.
val: a value to send as a single byte.
str: a string to send as a series of bytes.
buf: an array to send as a series of bytes.
len: the number of bytes to be sent from the array.
