Great video!!

[@nsnowaz]

This is very useful logic

[@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.

int ready_entrer=0;
int ready_sortir=0;
void setup()
{
pinMode (sensorPin1,INPUT_PULLUP);
pinMode (sensorPin2, INPUT_PULLUP);

lcd.init(); // initialize
lcd.backlight();
lcd.setCursor(4,0);
lcd.print("COUNTER");
lcd.setCursor(0,1);
lcd.print("No Visitors ");
delay(200);

Very useful, Thanks

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

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?

[@photonixenlighteningworld5026]

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

[@manjunathchindi9803]

I need circuit diagram for this

[@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?

[@artawanaget2417]

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

[@kawaii7054]

Why is there a buzzer in the code?

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

[@sirmike7619]

can you gave the original code

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

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

[@ztech891]

Please update the code ....

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