- Demonstrates the use of SerialEvent(). - Send multiple variables using a call-and-response (handshaking) method, and ASCII-encode the values before sending. - Send multiple variables using a call-and-response (handshaking) method. - Turn a LED on and off by sending data to your board from Processing or Max/MSP. - Use two of the serial ports available on the Arduino and Genuino Mega. - Send data to the computer and graph it in Processing. - Move the mouse to change the brightness of an LED. 
- Demonstrates Arduino's advanced serial output functions. You'll use the Arduino Software (IDE) serial monitor to send strings like '5,220,70' to the board to change the light color. The values are parsed into integers and used to determine the color of a RGB LED. Often people use a comma to indicate different pieces of information (this format is commonly referred to as comma-separated-values or CSV), but other characters like a space or a period will work too. > 04.Communication > ReadASCIIString Read ASCII String This sketch uses the () function to locate values separated by a non-alphanumeric character. 
By framing your data into packets with a 'start-of-frame' byte the receiver will be able to more quickly detect when a communication error has occurred and resync with the data stream. The reason for this is because serial communication is unreliable, sometimes bytes will get lost or there may be noise on the wire that causes extra bytes to be received. This is where you wrap the message you are going to send with a special indicator so your receiver can tell where the beginning and ends of messages are. If you are not already, you should consider using a message framing scheme. And the result of x and y has to be send in HEX, 16 bits. Arduino Serial Communication, Bytes, Bases. Serial.I'm trying to create an Arduino interface for the DMX software Freestyler, but struggling to parse the data received due to knowing the encoding of the data received.
