 * Simple printf for writing to an Arduino serial ports eg. Serial..Serial3. Note: format
 * specifier must match actual argument type eg. int32 should be formatted as %l, not %d.
 * Usage: Serial_printf(Serial,"%d\n",vars);
 * %B  binary (d = 0b1000001)  %b  binary (d = 1000001)      %c  character (s = H)
 * %d/%i  integer (d = 65)     %o  boolean on/off (d = On)   %%  escaped percent ("%")
 * %f  float (f = 123.45)      %.3f/%3f  float (f = 123.346) %l  long (d = 65)
 * %s  char* string (s = xyz)  %X  hexadecimal (d = 0x41)    %x  hexadecimal (d = 41)
