**4060 Delay timer** - In this project we added 30 to 60 minutes delay off timer and 5 to 15 minutes delay on timer means that the timer will remain close for about 30 to 60 minutes and open for about 5 to 15 minutes. - In this project we use 2 timer to add two different times of on and off delay. - First when we give supply to the timer 1 we get the delay off of about 30 to 60 minutes. After that when the interrupt occur or the timer get started after the delayit also triggers the second timer and it also get started after 5 to 15 minutes when the timer gets started after the delay the output of the second timer triggers the transistor which is acting as push button both timer are reset and the whole process start again
