[@unofficial5274]

I cannot find the link in description which is added to preferences

[@SaiSan-z8r]

which blynk version did u use urgent broo??

[@dr2man]

Do you have a video that would show me how to hook up a simple reed switch yo an ESP32 to indicate a door opening and closing along with code using Blynk?

[@yawarsaeed6499]

Hi, In addition to Photo taken by ESP32 Cam can we add Intercom for voice communication between ESP32 CAM & Mobile phone with Blynk app as this will be an ideal system to make contact with remotely located person. Does the Blynk app has this voice communication tool to support this option. Awaiting your earliest response. Thanks & kind regards.

[@electronic7979]

Excellent project

Bro please make an video of face recognization door lock

[@4LfaXaadiYT]

Can you please help me where can I get all the things you've used in circuit, I really need this project as I really found it so helpful and want to show this to my teacher as sem end project. Please I request to help me out

[@anjalikakkar7273]

Hello, did you buy the Blynk app complete version to use the image gallery tool and camera module or is there a free version available? Please let me know, need it for my IoT project. Thank you so much!

[@r.pranay4486]

For this project upload speed and flash frequency are how much if we are connecting with arduino.it is only taking the values ,that you showed in esp-32 cam with Arduino Uno video.the both values are different and programmer name is also different.so,can we use upload speed is 115200 and Flash frequency is 40mhz instead of 921600 and 80mhz? And programmer is AVR ISP instead of AVRISP mkll?? Pls reply

[@nappalaganas5748]

Very nice project amd well explained, could you create the same but could view from another network or intermet away from my home. Thank you so much.

[@r.pranay4486]

So we can connect according to the video and we can upload the code.does there will be any problem with this?both ftdi232 and this programming with Arduino will be similar and can give same results know?? Pls reply

[@chesterallancustodio16]

How did you connect the esp32 anf the board?? When i connect the two the status in the blynk apps is offline

[@pranav.b2680]

An error occured while compiling the code in the 122nd line - Blynk.notify ("Someone is at the door..."); what is the solution to this ? plese respond ASAP Thankyou :)

hi mate. instead of unluck the door with the locker, I want to drive a step motor. I have the firmware to drive the step motor. can you please help me just to integrate that in to your code. when press unlock button, insted of unlocking the door with your locker, it will drive the step motor. thats all I want to integrate. can you please help?

Bro, fantastic tutorial. Can u teach on how to capture a photo from an IP camera and send it to Telegram and LINE Notify. I am using Dahua IP camera and the image preset with high resolution and cannot be changed, I don't manage to get it to work with my NodeMCU. I m seeking for this high and low but haven't seen anyone doing that and u might be the 1st person.

[@indhujag5920]

I too want explanation for this question.

[@r.pranay4486]

Does the esp32-cam should connect to WiFi ?that means does it should be in the WiFi range.and what about phone?does phone should be connect to WiFi always?

[@TechStudyCell]

ESP 32 & phone should be connected with same WiFi

[@r.pranay4486]

Do we have to connect any led at pin4.as you told in code.but it is not there in circuit diagram. Where we have to connect the two terminals of led?does any resistor is needed

[@TechStudyCell]

There is a inbuilt LED on ESP32CAM, connected with GPIO 4. The LED will turn on when ESP32CAM will take pictures.

[@nitinjain786]

This is exactly what I was looking for my home.. here is additional requirements 1) Add 1 button to open door from inside home without using mobile app. 2) Add sensor to check whether door is open or closed, that is current state of door 3) Add delay of 15 second to automatically closed the latch. That means whenever user press open door, then latch is open for 15 second and after expiry of 15 seconds, if door is in closed state then latch is closed 4) whole system need to work on 230v 5) As soon as visitor press button, it's pictures should be captured and sent to app When all above is done and u have polished device, I will purchase it.. customer is ready

[@TechStudyCell]

Thanks for the suggestions. But with new Blynk you can not send pictures. So I will try it with Telegram.

[@nitinjain786]

@@TechStudyCell integrate it with WhatsApp or any other option, key is as soon as visitor press button, his picture should be published, if possible at least with 5 sec interval.. This will be perfect solution
