Serial is used for communication between the Microduino / Arduino board and a computer or other devices. All Microduino / Arduino boards have at least one serial port (also known as a UART or USART): Serial. It communicates on digital pins 0 (RX) and 1 (TX) as well as with the computer via USB. Thus, if you use these functions, you cannot also use pins 0 and 1 for digital input or output.

Serial Baud Rate
Sets the data rate in bits per second (baud) for serial data transmission. For communicating with the computer, use one of these rates: 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, or 115200.

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.

Serial Print
Prints data to the serial port as human-readable ASCII text. This command can take many forms. Numbers are printed using an ASCII character for each digit. Floats are similarly printed as ASCII digits, defaulting to two decimal places. Bytes are sent as a single character.

Serial PrintLn
Prints data to the serial port as human-readable ASCII text followed by a carriage return character (ASCII 13, or '\r') and a newline character (ASCII 10, or '\n'). This command takes the same forms as print.

Serial PrintLn(Hex)
Prints a number to the serial port as human-readable hex format number. Followed by a carriage return character (ASCII 13, or '\r') and a newline character (ASCII 10, or '\n').
Serial Availability
Get the number of bytes (characters) available for reading from the serial port. This is data that's already arrived and stored in the serial receive buffer (which holds 64 bytes). available() inherits from the Stream utility class.

Serial Read String
Reads characters from the serial buffer into a string. The function terminates if it times out.

Serial Read String Until Character Delimitation
Reads characters from the serial buffer into a string. The function terminates if the terminator character is detected or it times out.

Serial Read
read
Reads incoming serial data.

peek
Returns the next byte (character) of incoming serial data without removing it from the internal serial buffer. That is, successive calls to peek will return the same character, as will the next call to read.

parseInt
Looks for the next valid integer in the incoming serial stream.

parseFloat
parseFloat returns the first valid floating point number from the Serial buffer. Characters that are not digits (or the minus sign) are skipped. parseFloat is terminated by the first character that is not a floating point number.

Serial Flush
Waits for the transmission of outgoing serial data to complete.

Software Serial Setup
Initializes the pins for SoftwareSerial. Starting SoftwareSerial is done with the begin function block.
