Code for Activating a Led After 2 Minutes and Will Blink After 30 Seconds Interval

Use a commonly available USB power pack re-charging from mains and powering the Arduino. Use a light source directly powered by main and optically couple that to an Arduino. There are plenty of examples on the web where an Arduino is used to detect light. Once triggered, write some additional code to blink the led. Since you are not doing anything other than timing, you can use the delay Arduino library to time events

Can anyone help me to build a code which will activate a LED after 2 minutes when the power supply is cut off and blink that LED after a time interval of 30 seconds.

I want to import the code on Arduino-Uno.

I will power the Arduino with cell and assign two pins as sensor if they are connected to each other than every this is fine if they are cut the Arduino will blink the LED after 2 minutes and will keep blinking at 30 seconds interval
