CompTimer_v0_32.ino

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.
