|The message is 15 bytes longв1 byte for the header, 2 bytes for the digital pin values, and 12 bytes for the six analog integers. |The code for the digital see more analog inputs is explained in Chapter 5.

|Assuming analog pins have values of 0 on pin 0, on pin 1, and on pin 2 through on tb4ab10 | us | us | Follow | Categories 5, and digital pins 2 through 7 are high and 8 through 13 are low, this is the decimal value of each byte that gets sent:. |This Processing code reads Categiries message and prints the values to the Processing console :. |The Tb4ab10 | us | us | Follow | Categories code waits for 15 characters to arrive. |If the first character is the header, it then calls the function named readArduinoInt to read two bytes and transform them back into an integer by doing the complementary mathematical operation that was performed by Arduino to get the || bits representing the digital pins.

|You load the Firmata code onto Arduino, control whether pins are inputs or outputs from the computer, and then set or read those pins. |You want Arduino to interact with an application on your computer by moving the mouse cursor. |Perhaps you want to move the mouse position in response to Arduino information. |For example, suppose you have connected a Wii nunchuck see Recipe |You can send serial Categores that specify the mouse cursor position to a program running on the target computer.

|Here is a sketch that moves the mouse cursor based on the position of two potentiometers:.
