/*Arduino Protothreading Example v1.1by Drew Alden (@ReanimationXP) 1/12/2016- Update: v1.1 - 8/18/17 Arduino 1.6.6+ prototyping changed, small fixes. (create functions ahead of use, removed foreach and related library). Note that TimedAction is now out of date. Be sure to read notes about TimedAction and WProgram.h / Arduino.h errors.*///COMPONENTS/*This code was made using the Sunfounder Arduino starter kit's blue LCD.It can be found at Amazon.com in a variety of kits.*///THIRD-PARTY LIBRARIES//these must be manually added to your Arduino IDE installation//TimedAction//allows us to set actions to perform on separate timed intervals//http://playground.arduino.cc/Code/TimedAction//http://wiring.uniandes.edu.co/source/trunk/wiring/firmware/libraries/TimedAction#include //NOTE: This library has an issue on newer versions of Arduino.

The LiquidCrystal library works with all LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them by the 16-pin interface. One example circuit: * LCD RS pin to digital pin 12. * LCD Enable/E/EN pin to digital pin 11 * LCD D4 pin to digital pin 5 * LCD D5 pin to digital pin 4 * LCD D6 pin to digital pin 3 * LCD D7 pin to digital pin 2 * LCD R/W pin to ground * LCD VSS pin to ground * LCD VCC/VDD pin to 5V * 10K resistor: * ends to +5V and ground * wiper (middle) to LCD VO pin (pin 3) *Backlit Displays: * LCD K pin to ground (if present) * LCD A pin to 220ohm (red red black black (brown)) resistor, then resistor to pin 9 This example code is in the public domain. http://www.arduino.cc/en/Tutorial/LiquidCrystal *///GLOBALSint backlightPin = 9; // used for backlight fadingint timerCounter = 0; // incrementing counter. will crash eventually.int stringNo = 0; //which text string to show// "16 CHARACTER MAX"char* stringArray[]={"Check it out...
