This function does not seem to be in the sketch or the UniversalTelegramBot library but there is a function named sendPhoto() and one named sendPhotoByBinary()

Where did you get the sketch from ?

I moved your topic to a more appropriate forum category @kurniawantakulowa_1.

The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.

In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.

Thanks in advance for your cooperation.

but when i try this code without door lock code,it is work. or maybe i have something wrong when i combine these two codings? i mean camera code and door lock code.
please help me to combine the two codings.

sorry, i have two codings, between camera code and door lock code. when i tried both code separately, they worked fine, but when i tried to combine the two codings, there was an error (error compiling of board ESP32 Wrover Module).
please help me dude.

how do I combine the coding below? I want to make a project to monitor the house to remain safe with two methods, namely monitoring via camera and also providing a password on the door.

Your code tags worked for the first sketch but did not work for the second sketch.

I just finished changing it, please take a look again :cry:

9

Now I see only one sketch. Did you combine them?

10

between CODINGAN 1 and CODINGAN 2

12

Please post each sketch in its own code tags.

The first step for combining two sketches is to understand the meaning and purpose of each line of code in each sketch. Have you done this?

If so:

  1. combine the global variables from the second sketch into the first sketch, removing any duplications.
  2. combine the added functions (not setup() or loop()) from the second sketch into the first sketch
  3. combine the contents of setup() from the second sketch into setup() of the first sketch, removing any duplicate lines. Same for loop().

Up to now you have not mentioned that you are trying to merge two sketches into one

Please post the 2 separate sketches that you say work OK

I have merged your cross-posts @kurniawantakulowa_1.

Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.

Repeated cross-posting can result in a suspension from the forum.

In the future, please only create one topic for each distinct subject matter. This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide. It contains a lot of other useful information. Please read it.

Since you inappropriately created the cross-post in the Nano ESP32 category even after I have repeatedly told you not to do that, I have given you a temporary account suspension. I hope that when you return to the forum you'll be more respectful of our community.

Thanks in advance.
