/**
 * @example CompTimer.ino
 * 
 * @par How to Use
 * This example shows that ,when the OFF button component on the Nextion screen is released,
 * the timer will opened,the text will show number changed and push the ADDTIME button timer 
 * cycle value will increase,when push the DECTIME button timer cycle  value will reduce.
