From db605dd18b11ecfb5cd9f92c721c52cb70543384 Mon Sep 17 00:00:00 2001 From: "David A. Mellis" Date: Mon, 1 Jun 2009 08:32:11 +0000 Subject: First integration of the Arduino code in Processing 5503: PreProcessor and Compiler have been integrated with changes to the Sketch. Compilation still has problems (Thread error on success, and can't handle non-pde files in a sketch). Modified the Mac OS X make.sh to copy the hardware, avr tools, and example over. Removing some of the antlr stuff. Disabling the Commander (command-line execution) for now. Added Library, LibraryManager, and Target. Added support for prefixed preferences (e.g. for boards and programmers). --- libraries/Stepper/examples/MotorKnob/MotorKnob.pde | 40 ++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 libraries/Stepper/examples/MotorKnob/MotorKnob.pde (limited to 'libraries/Stepper/examples/MotorKnob/MotorKnob.pde') diff --git a/libraries/Stepper/examples/MotorKnob/MotorKnob.pde b/libraries/Stepper/examples/MotorKnob/MotorKnob.pde new file mode 100644 index 0000000..062cac9 --- /dev/null +++ b/libraries/Stepper/examples/MotorKnob/MotorKnob.pde @@ -0,0 +1,40 @@ +/* + * MotorKnob + * + * A stepper motor follows the turns of a potentiometer + * (or other sensor) on analog input 0. + * + * http://www.arduino.cc/en/Reference/Stepper + */ + +#include + +// change this to the number of steps on your motor +#define STEPS 100 + +// create an instance of the stepper class, specifying +// the number of steps of the motor and the pins it's +// attached to +Stepper stepper(STEPS, 8, 9, 10, 11); + +// the previous reading from the analog input +int previous = 0; + +void setup() +{ + // set the speed of the motor to 30 RPMs + stepper.setSpeed(30); +} + +void loop() +{ + // get the sensor value + int val = analogRead(0); + + // move a number of steps equal to the change in the + // sensor reading + stepper.step(val - previous); + + // remember the previous value of the sensor + previous = val; +} \ No newline at end of file -- cgit v1.2.3-18-g5258
