The ESP32 camera is going to host a video streaming web server that you can access with any device in your network. You can integrate this video streaming web server with popular home automation platforms like Home Assistant or Node-RED. You can use the preceding links or go directly to MakerAdvisor. Follow the next steps to build a video streaming web server with the ESPCAM that you can access on your local network.
View raw code. Before uploading the code, you need to insert your network credentials in the following variables:. Then, make sure you select the right camera module. Follow the next schematic diagram:. Many FTDI programmers have a jumper that allows you to select 3. Make sure the jumper is in the right place to select 5V.
Open the Serial Monitor at a baud rate of Now, you can access your camera streaming server on your local network. A page with the current video streaming should load. Continue reading to learn how to integrate with Home Assistant. The following image shows us testing the video streaming camera.

You just need to create a Template node and add the following:. We intend to integrate this with Node-RED too. The face recognition and triggering events might be a bit more difficult. Try powering the camera with 5V. Some readers reported improvements in wifi signal after powering with 5V. Regards, Sara. Check the jumper 0K resistor by the antenna connector is in the proper position for the antenna desired.
When iam compile the code. I meant completely integrating it in Node-RED — available on the dashboard as a viewable feed, face recognition triggering events, etc. Do you have the ESP32 add-on installed? Any suggestions on how to use it to capture video?
Hi Ben. We intend to do a similar project in the future. The example code provided in the arduino IDE, also takes photos.If you want to put them to work, all you need is a receiver, a network-enabled microcontroller, and some code.
In his latest video, [Aaron Christophel] shows how easy it can be. In this case [Aaron] is using the Telegram API to send out messages that will pop up with a notification on his phone when a door or window is opened. But you could just as easily use something like MQTT, or if you want to go old-school, have it toggle a relay hooked up to a loud siren. Specifically, [Aaron] walks the viewer through the process of scanning for new MHz devices and adding their unique IDs to the list the code will listen out for.
Unsurprisingly, Espressif is developing even newer product and the ESPS2 was in the hands of some beta testers last year. You might notice this is less than the ESP The microcontrollers are cheap, the sensors are cheap, even the motors are cheap.
So why are all the good wheeled robotics platforms so expensive? So he did what any good hacker would do, and built a better version himself. Interestingly, [Dimitris] decided to go with a chassis made from two PCB panels. The motors, mounted to small angled brackets, bolt directly to the lower PCB. Each JGB gearhead motor comes complete with an encoder that allows your software to determine speed, distance, and direction. The upper PCB connects to the lower with several rows of pin headers, and plays host to whatever electronics payload you might be experimenting with at the time.
For the controller, [Dimitris] says the ESP32 is hard to beat by pretty much any metric you want to use. But he also says that every effort has been made to ensure that you could switch out the microcontroller with something else should you want to spin up a customized version.
Still too much? Or see if you can get lucky and pick up a cheap robot from the clearance rack and hack it. Hackaday editors Elliot Williams and Mike Szczys gab on great hacks of the past week.
Fans of the ESP are going to love this tool that flashes and configures the board, especially for Sonoff devices. Take a look at the links below if you want to follow along, and as always tell us what you think about this episode in the comments!

No, seriously, we are! Telegram Bot. Telegram Bot Re: Telegram Bot The reason why your code does not work is that Telegram.
If you want a telegram bot library written for esp under Arduino Ide, have a look to my github repository. I'm interested to have your feedback. Giancarlo Dear friend! WiFi connected IP address: This library is the one to be used with WiFi shield that is a brandnew product from Arduino that will be available very soon. When I wrote you, there was the ESPTelegramBot library in my repo, now it is no longer there I can send the correct library to you in attachment.

It happens to all of us: you are at home, but for whatever reason you don't hear the doorbell, even though there really is a visitor at the door.
If it's family or a close acquaintance, chances are they'll grab their mobile phone and try to find out if you're home, but not everyone has your phone number at hand.
It's only really annoying when you've stayed home especially because an order is being delivered that you're desperately waiting for and the deliveryman leaves unfulfilled. Deliverers usually don't have the patience or the time to call again and later in the day you'll find a note in your mailbox that you can pick up the parcel somewhere or that it will be offered again on another day. With the project we are presenting here, the chance of missing the doorbell is much smaller: as soon as the doorbell rings, this circuit sends a message to your smartphone or computer on which the Telegram app is running, so that almost everywhere even when you are not at home!
Telegram is an instant messaging service that can best be compared to Whatsapp in terms of functionality. Both services are linked to your mobile phone number, and Telegram also offers the possibility to register your user name, so that your account can also move with you when you get a different mobile number. There are even more more or less subtle differences and if you want to know more about it, you can find more than enough comparisons between the two applications on the internet.
In this article we will see that with Telegram it is very easy to work with bots and - in this case - to communicate and control with an ESP32 remotely, in this case to send a message when a key is pressed and to translate a possible answer into the activation of a relay.
Of course, the possibilities are not limited to this relatively simple application, the concept can easily be adapted and expanded. Here we are going to use this -very simplistically said- as a smart module that interacts with the outside world via WiFi.
Together with the well-known Arduino development environment and the UniversalTelegram bot library, developing applications like this is a piece of cake.
However simple the application may be, during the development of this project we had to deal with a very special phenomenon, as a result of which it ultimately took a lot more time than expected and planned. Imagine: the source code compiles without error messages, upload to the ESP32 is also fine and the circuit initially seems to work as expected. To be more precise: something is happening, but further research shows that the microcontroller always resets when a message arrives via Telegram.
All checked and tried, no mistake to discover. So let's recompile and test on another computer and to your amazement the ESP will do what is expected of it!
Check again if both computers have the same versions of the Arduino IDE and libraries, no difference to be found. Finally, on the first computer, we completely removed Arduino no ordinary uninstall, which apparently leaves remnants in -hidden- folders anywayinstalled it freshly and all problems are gone. What the problem was I learned that the Arduino IDE can be very unpredictable, even if it was the first time we encountered such a thing.
And let's agree: also the only and last time! With minor modifications to the software, this project can be used with any ESP32 or module, but for this project we have chosen the M5Stack ESP32 Basic Core module which is available in the Elektor shop. It is a nice compact module in a neat housing with a graphical display, push buttons, a speaker and a built-in rechargeable battery.Not a member?

Telegram is a messaging application which is used to send text, images or video messages free of cost. It also allows using other API to create programs to integrate Telegram in their applications. There are special bots which do not need phone number to set up and can be interfaced with any embedded or software application to trigger some event using telegram text messages.
Sign Up if you are going to use it for the first time with your country code and mobile number. It will ask for OTP code for verification. After successfully sign up, search for BotFather and open it. It will show set of codes which can be used to create and edit bots.CCTV Motion Detect Telegram Dengan ESP32 CAM
Now you have to choose a name for your bot. Type the name of your bot and click on send. This username should be unique. After giving username you will receive a text from BotFather about your new bot and will get a token for the new bot. This token will be used in code for NodeMCU. Click on the link given in the message to go to your new chat box of the bot and then click on Start.
You can now send your commands by send a text message from Telegram app. This library is easy to use and very straightforward for interfacing Telegram with ESP chips. CTBot library by Stefano Ledda comes with inbuilt examples.

String token stores the unique token number you got after creating your bot. D0 is the digital output pin for changing the state of the relay.Since the beginning ofprices have fallen sharply. The ESP32 offer is now very diversified. Here is a brief overview.
The range now has 6 models. It targets a wide variety of applications, sensor networks, voice encoding, music streaming and MP3 decoding. FL connector. Technical documentation ESP32 7. This less powerful module should also be less energy intensive, so better suited for battery-powered applications. It is the ESP32 module that is most commonly used in development board manufacturers.
Here is also the general identification of the pins. On the other hand no evolution regarding the input voltage and output, it is always 3.

There are some at all prices. Can not test them all. We can just rely on the opinions left by buyers. However, Geekcreit is now a recognized manufacturer.
We also find his board under the name MUST recently. The Geekcreit is equipped with a micro-USB connector for power, programming and debugging. It is very well supported by the Espressive SDK. Full selection of generic ESP32 development boards. The latest is the Wemos LoLin32 presented in this article. It is an excellent choice. Equipped with 4MB of memory and a micro USB connector for programming, it is narrow and equipped with an external LiPo battery connector. It is supported natively by the Espressive SDK.
Full selection of Wemos LoLin32 development board. Full selection of Wemos LoLin32 Lite more compact development board. It comes with an expansion board with 10 connectors that appear to be in Intel Grove format.
The board is sold under the Wemos brand and moreover it seems to be recognized as such by the SDK. If you need to develop applications that use the LoRa network, there are now very economical development boards based on ESP Choose the radio module that corresponds to the frequency used in your country. Each radio module can be configured in a particular frequency. There is an optimal frequency for each module. If the compactness of the development board is paramount for your project, there are very compact boards.
Let us not forget that the ESP32 also incorporates Bluetooth, which makes it possible to make less expensive and more compact setups than starting from an Arduino nano V3 combined with a Bluetooth module HC Attention to the module, very often it is an ESPS which is delivered in the kit. Full selection of compact ESP32 development board. Full selection of soldering module ESP The ESP32 introduces some changes in the programming.
It took a while for the main bookstores to be adapted to run on the new Espressif SoC. This code editor is very interesting if you want to share code with different micro-controllers. PlatformIO is also able to update the program remotely including via internet.
