Description Writes a value to the servo, controlling the shaft accordingly. On a standard servo, this will set the angle of the shaft (in degrees), moving the shaft to that orientation. On a continuous rotation servo, this will set the speed of the servo (with 0 being full-speed in one direction, 180 being full speed […]

Description Attach the Servo variable to a pin. Syntax servo.attach(pin) servo.attach(pin, min, max) Parameters servo: a variable of type Servo pin: the number of the pin that the servo is attached to min (optional): the pulse width, in microseconds, corresponding to the minimum (0-degree) angle on the servo (defaults to 544) max (optional): the pulse […]

Description rewindDirectory() will bring you back to the first file in the directory, used in conjunction with openNextFile().

Syntax file.write(data) file.write(buf, len) Parameters file: an instance of the File class (returned by SD.open()) data: the byte, char, or string (char *) to write buf: an array of characters or bytes len: the number of elements in buf Returns byte: write() will return the number of bytes written, […]

Description Read a byte from the file. read() inherits from the Stream utility class. Syntax file.read() Parameters file: an instance of the File class (returned by SD.open()) Returns The next byte (or character), or -1 if none is available. See Also － available() － peek() － write() － Stream.read() Libraries Reference Home The text of […]

Description Get the size of the file. Syntax file.size() Parameters file: an instance of the File class (returned by SD.open()) Returns the size of the file in bytes (unsigned long) Libraries Reference Home The text of the 86Duino reference is a modification of the Arduino reference, and is licensed under a Creative Commons Attribution-ShareAlike 3.0 […]

Description Seek to a new position in the file, which must be between 0 and the size of the file (inclusive). Syntax file.seek(pos) Parameters file: an instance of the File class (returned by SD.open()) pos: the position to which to seek (unsigned long) Returns true for success, false for failure (boolean) See Also － position() […]

Description Print data, followed by a carriage return and newline, to the File, which must have been opened for writing. Prints numbers as a sequence of digits, each an ASCII character (e.g. the number 123 is sent as the three characters ‘1’, ‘2’, ‘3’). Syntax file.println() file.println(data) file.print(data, BASE) Parameters file: an instance of the […]
