[@mattbodycote2914]

are you able to give a shopping list of items for this, its exactly what I'm looking for

[@jordanwilliams8132]

Can this code be modified, to count independently by the two sensors and make a sum of count into a seven segment display?

[@Drxxx]

Great video!!

[@andalrico4204]

Can you make one without using arduino? Is it possible to use 7 segment, ic, ir sensor and other components to make the project?

[@ketsireetantiwit6033]

Very useful, Thanks

[@nsnowaz]

This is very useful logic

I want to count the exact number of visitors entering and exiting my museum. Where can the parts used to make it be found? How much will the price be? How will it cost in total?

[@loopfi8835]

The code you sent works differently from the show on the video. to count people entering the room requires going through 2 sensors, but the code you posted in the description is working with each sensor, not using both at the same time. Please post the new code.

Why is there a buzzer in the code?

It will be better if you explain your code in your video .

Hello sir, your code for fixing the issue of continously counting when the person stays on the first sensor is NOT WORKING, could you please fix it sir? Thank you so much

Yuo,
The IR sensor is sucks, it not working for this project,
Because the distant is low, only 10cm

[@boopeshkumarprabhakaran]

in my sitution it goes like -1, -2 etc in counts...how to fix the count not go less then 0
