in this sam,e as led on off is working witj entering ip addres in text box ..
but for video streaming throught activity starter is coonectivity do like this for wifi is working or not or just we have to acces only not need of wifi connectivity in textbox by entering ip addres!!
I have not tested it, but you can have the same web server for video transmission and to turn on / off the LED.
Example: TextBox1.Text: http://192.168.9.21
It depends on the code of the ESP32
OK thanks for ur guidence !
- Turn on/off LED4 of the ESP32-CAM.
p247i_ESP32_Cam.aia (2.3 KB)
The ESP32-CAM module has a high luminosity LED, we are going to turn it on/off from an application.
We are going to use the library that we saw in one of the previous post:
https://github.com/yoursunny/esp32cam
The Clock has an Interval of 800 ms, every that time a CAPTURE will be made.
Through the Buttons we send an on/off order to LED4.
We can also see the video in Stream, to turn it off we must wait about 35 seconds.

- ESP32-CAM captures images and uploads them to Google Drive. (I)
Previously, it is interesting to carry out this example of @TIMAI2 to upload and update files in Google Drive:
To carry out this example I will follow this tutorial in Spanish:
ESP32-Cam: Subir fotos a Google Drive – Software | IoT
We download the necessary files to a folder:
Note that the name of the Sketch is the same as its directory and that the Base64 Library is in the same directory.
You copy the content of the codigo.gs in Google Script.
ESP32-CAM will capture an image every minute, convert it to Base64, and upload it to Google Drive.
This tutorial in Spanish:
http://kio4.com/arduino/247_Wemos_WebCam.htm#drive
- ESP32-CAM capture image and update that image in Google Drive (II).
We are going to change the Script code, we will use part of the @TIMAI2 code to update the image that we will call capture.jpg
function doPost(e) {
var data = Utilities.base64Decode(e.parameters.data);
// var nombreArchivo = Utilities.formatDate(new Date(), "GMT-3", "yyyyMMdd_HHmmss")+".jpg";
var filename = "capture.jpg";
var blob = Utilities.newBlob(data, e.parameters.mimetype, filename);
var folder, folders = DriveApp.getFoldersByName("ESP32-CAM");
if (folders.hasNext()) {
folder = folders.next();
} else {
folder = DriveApp.createFolder("ESP32-CAM");
}
var existing = folder.getFilesByName(filename);
if (existing.hasNext()) {
var file = existing.next();
if (file.getName() == filename) {
fileID = file.getId();
// Drive.Files.update({title: filename, mimeType: mimetype}, fileID, blob);
Drive.Files.update({title: filename, mimeType: file.getMimeType()}, fileID, blob);
}
} else {
blob = Utilities.newBlob(data, e.parameters.mimetype, filename);
fileID = folder.createFile(blob).getId();
}
// var file = folder.createFile(blob);
return ContentService.createTextOutput("Completo.")

hello sir,
my quation was by using esp 32 cam module can i controlled other 6 leds through mit app through wifi connecetivity and configuring esp32 cam as web server meanse in local area network ..... beacuse esp32 cam having 10 gpios but some are used for the camera in bulid module so can u help me in this?
In this tutorial you can see the ESP32-CAM pinout:
The following pins are internally connected to the microSD card reader:
but if you don't have SdCard, maybe you can use it, I haven't tried it.
These pins can be connected to a 16-Channel CD74HC4067 multiplexer module and get 16 outputs.

- Loading the Sketch using an Arduino UNO.
Instead of loading the Sketch through an FTDI module, we can load it with an Arduino UNO.
But, attention, the Arduino IDE must be less than 1.8.13, if it is equal to or greater, the Programmer will not work: "No programmers available for this board"
Set this configuration:
In this video it is well explained:
https://www.youtube.com/watch?v=q-KIpFIbRMk
- Add a button to the web page to turn on/off LED4, flash led.
We consult the following tutorial:
- Another Video Streamer with the WebViewer component.
It can transmit with HTTP and RTSP.

#endif
#ifdef ENABLE_RTSPSERVER
WiFiServer rtspServer(8554);

hi there, i had some question, in your esp code there is no led, and if i add a led 4 from http://kio4.com/arduino/247_Wemos_WebCam.htm#led4, when streaming the led button doesnt work, how to make the led button work when streaming?, thanks...

when streaming, the led button is not working, how to make it work while streaming?
While it is streaming it cannot be changed.
Hi,
firstly thanks for the great job.
I tested the .aia and .ino at #18, that doesn't show any, the code serial monite output OK with:
CAMERA OK
http://192.168.100.176
/cam.bmp
/cam-lo.jpg
/cam-hi.jpg
/cam.mjpeg
and my PC shown well of image, but my phone with: p247_ESP32_Cam MIT APP shown nothing but error:
net:: ERR_CONNECTION_TIMED_OUT. (I've modified the IP)
what can be?
Thanks
Adam
Hello Juan Antonio.
I want to make a project with ESP32CAM, but i never use it.
It's for farming purposes.
My question is, i look for info about from when to when the camera record in the wave spectrum range. (i need take a photo from Visible to NIR - Near InfraRed). With 1 camera, take a capture with the visible and then, with another NIR. (i have the idea of removing the polarizing filter of the camera, i already read about it).
I will do this for a educational project in Geology.
I think to use a slider because the photo must be of the same place and in need to MERGE the 2 captures in 1. I need to rich the VISIBLE photo with NIR info, that's the idea.
But from all i searched i didn't find info about the spectrum (from 450nm to 750nm from visible, and later for the NIR , the close IR in the spectrum).
I will follower all i read in your post to make part of this project.
BUT
Do you know where to find this info (ESP32CAM spectrum of light info)?.
Does the " 3.- App Inventor. VisorWeb. Utilizamos otra librería para evitar el error" example on the "http://kio4.com/arduino/247_Wemos_WebCam.htm" page work for you?
The OV3660 camera is slow and low resolution, I don't think you will get quality images. You can see some examples of images on Youtube https://www.youtube.com/watch?v=KTOlRj-VKlg
You can get its characteristics in...
https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/unit/OV3660_CSP3_DS_1.3_sida.pdf
Perhaps a better option would be to use a Raspberry Pi and a USB WebCam.
http://kio4.com/raspberry/24_webcam_usb.htm
Gracias Juan Antonio.
Well. I write you in english because you replay in english (even your look like to be a spanish talker :D)
All the info you share with me, will help me a lot.
The resolution in this case is HUGE in comparison of the resolution i must to use with sat images.
I work with images, and every pixel means 30x30m.
Here the pixels means mm in any case or cm, not m.
So the resolution have scaled A LOT.
A question. If I only want to take a picture (in the IR), there is a way to be explicit to take the capture with the 750 to 1100 range?
How can i take the photo (in the visible or with the IR)?
I read the manual you share with me, and explain, about light, focus, if you chose sepia, negative. BUT never This range (IR), i think all the time is talking about Visible.
By the way, I am more curious about this cameras, do you know a camera for IR only from 700 to 2500nm.
I can solve the problem with this.... BUT, only from 700-1100.
Is only if you KNOW, i do not want to disturb you or take more time from you. I will stop asking here, because I have a lot for working with all of this.
If you are interest i can share my project but for the long explanation i think could be possible to talk outside of the forum, because this could be VERY LONG TO EXPLAIN, and could be annoying to explain it here, taking too much space from the forum .
This project is for farming. GeoInformatic's. If you are interest i can send you a mp talking about the project. I do not want to break any rule in the posting process, that's all.
Again. Thank you for all.
