Please what is the longest distance that can be monitored by this project? I'd like to get you on a surveillance project if you're interested and the distance is long enough to fit the purpose.

I followed you tutorial to the letter! the signal pin is working (emits 3.2V and 0.2 mV every 3 seconds on my esp8266 board), the relay is identical to yours, and the relay does close when I connect the signal pin to it... but that is all it does, it remains closed till I turn it off or till I disconnect the signal pin. I tried connecting the relay directly to the board 5V power source and to the 5v external power... nothing works. Interestingtly the relay will also close when I tried different pins, like D8, but not D6... the signal pin is D7)!! please someone help/

i actually thought the visual reference for the connections was poor. but thank you for sharing i was able to eventually figure it out with you upload.

is there a way to increase the distance the Sonar picks up and draws?

Hello, can you tell me the value of the potentiometer?

Nicely Done! Very Nicely Done! Loved that you did a high level overview and presented all this great stuff, particular the code and not stretching it out to an hour long ramble of overly detailed matters I can sort through later at my own tie and pace. Nicely Done! Very Nicely Done!

Excellent videos straight to the point. Thank you

Hi, friend, the content is excellent, I have a project that uses the power on of the web server using four buttons and using a push button, also four buttons, could you help me put the authentication code in my code?

is a low voltage relay an option? like if you wanted to send a 12v signal instead

Isn't there a more simple way to do this with thermostats?

How can i increase the range above 40 cm..

how come my ultrasonic sensor is not working?

Password authentication on an unencrypted HTTP connection is a complete nonsense. Anyone in your network (or in the world if you port forward) can intercept the traffic and steal your password.

I don't understand how updateButton function works. You pass this function along with other atrributes to request->send_p for server.on("\"). But inside HMTL, where does it call this function? Also, you declare String pwmSliderValue in the main c++ code and then you declare var pwmSliderValue inside HTML. So they're linked together? When it says "return pwmSliderValue" which one? the one in main code or the one in HTML? Can you please explain this updateButton function?

parseİnt(float) does not exist it says can you help me?

Im going to test this, and if this solves my problems i will PRAY for you❤

hi, this is an awesome and straight forward instructional thankyou so much ive watched so many that dont work, im strugglig at the end it says "make sure that the font has been copied to the data folder of your sketch, and opens the sketch and goes gray.

What a helpful post. Thank you very much kind sir.

Can I use a lidar for the same concept I have a tf mini and keep running into problems

Muchas gracias\

I'd like to do something similar but instead of serving the web server from the ESP32 serve it separately and then just interface the IO between the two. This way it would presumably save a lot of processing on the ESP32. Except I don't know how to do it!

For me it does not work, i am trying to give my ESP8266 (That is functioning as a server for some domotica devices) a static IP, it is connected to my laptop hotspot. But for some reason it does not stay static..

Life Xavier......ton of thanks

You saved me, thank !

Is it possible to make different accounts for different purpose?

Thanks so much bro i really needed this for a school project ive been strugging to find a way so the ip is constant and wont change. Once again thank you so much!

Thank you, amazing project. I would like to ask you, after successfully I create this project, I am trying to do the following project. when the radar detect something I want one of my DJI Mini drone, to flight to that area. Can you please guide me how can I do it? Thank you in advance

what can i use for simulation withtout the board

what if I use ESPAsyncWebServer instead of Webserver?

Sorry, but i can't follow your speaking english. You are to fast. I can't understand it to translate it. What do you do with the files and folders without preferences.txt? On Raspberry Pi 4 I can't see "move to bin". Headerror!!

Thanks

Hello sir what is the use of potential meter. And sir please can you and button to adjust the temperature

Thanku so much ❤🎉 I watched some videos but nothing worked but this one worked❤

This is a script belong to Rui Santos isn’t it?

What about head/cool thermostat with another relay that would turn on a FAN to cool down? Any help appreciated. !

You can make a video of something similar but that controls the speed of a fan, the idea is to control the temperature of a wood oven. Wearing: 1. Arduino UNO R4 WiFi. 2. Thermocouple K with its controller. 3. 12Volt fan. 4. Arduino Cloud. The K thermocouple will be in the smoke box, the fan will supply variable flow air, this air will pass through the heat box and take it to the smoke box, the cloud application will control everything, ignition, the desired temperature, By giving it a temperature of 250°F in the App, it varies the fan speed to maintain the temperature. In the leds of the Arduino you can see the temperature in real time. Greetings.

excellent video

it doesnt work bro, can you help me

Code of how show temperature?

How to find Local ip Gateway Subnet Primary dns Mac address ??

Can you make the detection range higher like 100 m or 1 km?

Thank you so much. You made my life easier.

My esp8266 not connect mobile hotspot, ssid and password ok, but not connect😢😢

Ip address is not comming

Hi! I have a Chinese x99 motherboard that have some temperature sensors that doesn't provide the motherboard temperature. I'm searching a solution to this problem and I think to add in my case a fan controller. The controller interact with the motherboard through the usb 2.0 connector, but if the motherboard doesn't provide its temperature, I think that this link between fan controller and motherboard will not be useful. If I will use one of this Arduino-based temperature sensor, how can I transmit the results to the fan controller? Is it possible doing something like that? Thanks if you respond!

hello how to create a button on the web page to decouple thank

how can u increase the range of the radar and make it display on the processing (ex: 1m)

can we use Arduino uno r3
