can any one help me ... 
i am trying to write a code which will turn an led for a period of time,every day.for example to turn on the led 5pm to 6pm every day.but i can't add time.h header file.
The error message while compiling is "fatal error: Time.h: No such file or directory
compilation terminated."
i cant even check with the example program
"TimeAlarmExample.pde"
Did you download, unpack and import the time library?
http://playground.arduino.cc/Code/Time
i can't add time.h header file.
Can you see it if you do Sketch/Import Library in the IDE ?
If not then it is not where it should be. If Time.h is on your PC then where is it exactly
no there is not such message "i can't add time.h header file."
I am sorry but I don't understand your answer.
Do you have Time.h and where is it located ?
ok i got it
