Bidirectional Counter using IR sensors and Arduino.

IR sensor and Arduino used to make a Bidirectional counter

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.

[mattbodycote]

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

[photonixenlighteningworld]

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

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?

[andalrico]

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

[zgryx]

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

[artawanaget]

Please share the code with one door, like in the video 🙏

[varunbodile]

can any one tell me what type of Ir sensor is that

[NahidHasan-mcvy]

Sir programme not running please solve

[jordanwilliams]

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

[karanagrawal]

Please give the code for the sensor when we move left to right and right to left

[oj_alan]

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
