Hello, I have a question ... What if someone passed the first laser and stopped in the middle ? What to add to this code to resolve this issue?
Thank you so much in advance 😃😃

Great tutorial. Really helpful for a project that I am currently working on. I do have a certain question though. how did you determine the value of this LDR_MIN and set it to 950. Like how would one know that when a person is not standing and blocking LDR1, the value would read more than 950 ? thank you.

Can I have the code for this project, please?

Edit: How/where do I insert a 2-digit 7-segment into the circuit?

Please help, if I have to display the numbers of people on Lcd (not PC's) what will be the changes in code.

If you don't mind can you do visual studio 2012 Caesar cipher, it would really be helpful for my project.

Can you make a video on an arithmetic quiz generator that asks for details and appends in to a text file with the scores.

for some reasons unknown, after the code worked once, it fails to decrement and only increments in both directions. Is there anything I would have to do please?
