Hi sir, how to use two ultrasonic sensors(ultrasonic one for person IN and ultrasonic two for person OUT .
Thankssss.....This project is 100% workinggggg😁
Thank you so much
i have a doubt bro ...how to display both image and text in tft dispaly i want code and video for this project...pls bro help me
IN counter continously counting..please help
Is this project on tinkercard to simulate online?
How to install Library for wire
The Wire library is bundled with Arduino AVR Boards. If you installed the Arduino board, then you no need to install this library.
Can you show the circuit using tinker cad and paste the code here because i cant access the link. Hope to get the response asap

salam rocky bhai........
Hi
Hi thank you for this video but i want to ask whether if this project could be done using a LED matrix board instead of a LCD display?
i would really appreciate a quick response!!
Yes you can. You need to modify the program
Could u please share the code of this bidirectional visitors counter
Please check description for source code.
Hi Shameer, thanks for sharing the code for Visitor counter circuit. Would you be kind to tell me why is 29.1 in distance formula? I know it is related to sound, still can't figure out why is that. Also, can you explain why the counter for Total inside (or the code itself) allows negative values as it is now?
Thanks for your comment. Please check the below explanation
1. To measure the distance, I used the formula
Distance = (Speed of Sound * Time)/2.
Speed of sound is 0.034 µs. In the formula I used 1/29.1 which will give the same result.
Divide by 2 indicates, the sound needs to travel back and forth.
2. In this experiment it will give negative value. But in real time it is not possible. For example consider a supermarket entrance. If a person enter into the supermarket, then only he will exit. Without any entry, there won't be any exit in real time.
If you have any further clarifications, please feel free to comment.
Where is circuit diagram? The description link contain only your video thumbnail image
Sorry. Please check the link now. By mistake I have uploaded the thumbnail image instead of circuit. If you have any clarifications, please let me know.
Bro vcc supply voltage .
VCC = 5 v
Sir can we use this with IR sensor ?
Yes. You can.
Hi sir how to make limit for 10 people inside
Please try this code
//Tech Trends Shameer
//Visitor Counter
#include
#include
#define trigPin 13 //Sensor Echo pin connected to Arduino pin 13
#define echoPin 12 //Sensor Trip pin connected to Arduino pin 12
#define buzzer 7
//Create Liquid Crystal Object called LCD
LiquidCrystal lcd(11, 10, 5, 4, 3, 2);
int counter = 0;
int currentState1 = 0;
int previousState1 = 0;
int currentState2 = 0;
int previousState2 = 0;
int inside = 0;
int outside = 0;
void setup()
{
// Initialize the LCD
lcd.begin(16,2); //Tell Arduino to start your 16 column 2 row LCD
//Serial.begin (9600);
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
pinMode(buzzer, OUTPUT);
}
void loop()
{
lcd.setCursor(0, 0); //Set cursor to first column of first row
lcd.print("IN: ");
lcd.setCursor(8, 0);
lcd.print("OUT: ");
lcd.setCursor(0, 1); //Set cursor to first column of second row
lcd.print("Total Inside: ");
long duration, distance;
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration/2) / 29.1;
if (distance 7 && distance 10 || counter < 0)
{
lcd.setCursor(14, 1);
lcd.print(counter);
digitalWrite(buzzer, HIGH);
delay(100);
lcd.clear();
}
else
{
digitalWrite(buzzer, LOW);
}
}
bro code open aka mattuthu pls send pannuga bro 1week tha time irukku
Bro. Instagram la message panunga. Code anupren
Hello sir Shameer can i ask or could you please share the processing code for this project
The source is provided in the video description. There is no processing code for this project.
He is saying program sir.
Sir my LCD display ON aagamatinguthu enna pananum
Check power supply and circuit connection
@@TechTrendsShameer sir all connections is correct ahh than iruku power supply corect ahh than iruku but display ON aagala 😥
Adjust the potentiometer in I2C and try.
Bro circuit diagram please
Please watch the full video.
Sir program uploaded successful but not showing LCD display
Blank screen how to solve this problem?
Same problem here 😭
Bro programing
Check video description.
Sir where did you buy all the components?
Please check video description for components link.
Workaha current thevaiya anan
Yes. Needed.
@@TechTrendsShameer how to connect anna
Connect the other end of the cable to the laptop or power banker.
@@TechTrendsShameer I want contact you anan

Bro where is power supply
Connect to laptop or power banker.
boss nedd voice in ENGLISH
Sure Sir. This is an old video. Right now for all the videos I am doing in English.
Sir unga contact number venum
