/// Arduino SmartThings ThingShield On/Off with LED Example
|
||||
///
|
||||
/// Revised by Dan Ogorchock on 2017-02-10 to work with new "SmartThings v2.0" Library
|
||||
/// -Now supports automatic selectic of SoftwareSerial or HardwareSerial constructor
|
||||
/// depending on the Arduino Model.
|
||||
/// -If using an Arduino UNO R3, be sure to set the ThingShield switch to the D2/D3 position
|
||||
/// -If using an Arduino Leonardo, be sure to set the ThingShield switch to the D0/D1 position
|
||||
/// -If using an Arduino MEGA 2560, bbe sure to set the ThingShield switch to the D2/D3 position AND
|
||||
/// connect jumper wires between pins 2 & 14 as well as between pins 3 & 15.
|
||||
///
|
||||
/// DO NOT USE PINS 0,1,2,3,6 for I/O in your sketch as pins 0,1,2,3 are used by the ThingShield
|
||||
/// and USB communications to your computer. Pin 6 is reserved by the ThingShield.
