Thankssss.....This project is 100% workinggggg😁

[@TechTrendsShameer]

Thank you so much

Hi sir, how to use two ultrasonic sensors(ultrasonic one for person IN and ultrasonic two for person OUT .

[@Hk-or1cn]

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

[@kingofluck7728]

Is this project on tinkercard to simulate online?

salam rocky bhai........

Hi

[@TechNode23]

IN counter continously counting..please help

[@nirajdeshmukh8982]

Where is circuit diagram? The description link contain only your video thumbnail image

[@TechTrendsShameer]

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.

[@adrianpatruta8002]

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?

[@TechTrendsShameer]

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.

[@amansinjali5584]

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!!

[@TechTrendsShameer]

Yes you can. You need to modify the program

[@aqilidris4034]

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
