You will need a real time clock module (like the DS3231 module) and then a library that will allow you to read the time from the clock. When the time reaches your target, you turn the LED on.

What have you done so far?

[INTP]

Use an RTC Module.

Oh okay ... can you give me a sample code po turning a LED on at 8am and turn it off at 8:05?

Btw what is the library needed for the rtc module?

[INTP]

Buy the module. Look for RTC libraries. They will have code.
Get the clock working.
Then it's just as simple as an if condition for time.
