Why I cannot match the timeframe easily and show them on max console?
I have trouble of matching the number of the video to the selected ones.
Why is that?
I want to use this patch to communicate with arduino to trigger the solenoid, so when i run a video, at a certain time that is selected by me , the solenoid will be triggered. I also cannot print a,b,c and d on Max Console. Please help

what do the numbers you want to match represent? seconds? milliseconds?
in that case you should use getattr
Hi, I want seconds
Not necessary to use [getattr], you can also query time_secs with messages:
The main error in your patch might be that you are connecting the rightmost outlet of your [sel] to [onebang], but that rightmost outlet will output anything that doesn't match the values you entered.
You can also use [change] instead of your [onebang] + [delay] to filter out repetitions.
I also cannot print a,b,c and d on Max Console.
Not sure what a, b, c and d are relating to here. I can only see a being your [serial] port, but that's it.
