/*
Consider you are in and industry and you are working on a flow line where you have 3 Tasks.
Task 1, Task 2, Task 3.

Task 1 takes 5s to complete.
Task 2 takes 15s to complete.
Task 3 takes 10s to complete.

You have to include a counter so that whenever the task is completed, counter is incremented.
Each task should be completed 10 times.

Consider that the product from these three tasks have to be combined together, so it is mandatory that all the tasks are completed at the same time, so we dont have any idle time.

Also, after 10 products, a batch is completed. So, indicate the batch completion with an LED. You have to complete 3 batches, so indicate this with 3 separate LEDs.

You have to include a real time clock, along with this, the start time and end time of each batch should also be noted. Also, the start and end time of each task should also be noted and displayed.

A stopwatch should also be included in the project to view the time of tasks.

1 ->implement task to complete

add tasks that take time
5 sec
15 sec
10 sec

2->when one task completed a counter increments
each task count upto 10, i.e each task must be iterated/ completed 10 times

3->when task 1 task 2 and task 3 reaches 10 return a batch
when each task increments 10-> return a batch completed after every task complete by LED1,2,3
when all led blink or every task increment 10/completed 10 times, blink another led4

4->include a real time clock to note start and end time of each batch and each task

5->include a stopwatch to view time of every task(time to complete)
