This Example uses the push buttons to change the LED colors.
TI LaunchPad
Educational BoosterPack MKII
None. This basic example just uses your LaunchPad and BoosterPack only.
/* Buttons & LEDs example for Educational BoosterPack MK II http://boosterpackdepot.info/wiki/index.php?title=Educational_BoosterPack_MK_II Turns on and off Green & Blue light emitting diodes(LEDs) connected to digital pins 38 & 37, when pressing pushbuttons attached to pins 33 & 32. The circuit: * LED attached from pin 13 to ground * pushbutton attached to pin 2 from +5V * 10K resistor attached to pin 2 from ground created 2005 by DojoDave <http://www.0j0.org> modified 30 Aug 2011 by Tom Igoe modified Apr 27 2012 by Robert Wessels modified Dec 03 2013 - for Educational BoosterPack MK II by Dung Dang modified May 23 2014 - corrected pin for buttonOne This example code is in the public domain. http://www.arduino.cc/en/Tutorial/Button */ // constants won't change.
