Спасибо большое. Очень хорошее видео и понятное! А не могли бы вы снять видео и объяснить, как получать данные с датчиков? Например если на машинку установить дальномер, датчик освещенности, температуры и прочее... А так же, ещё бы и обратную связь сделать, для получения статуса управления, если вдруг машинка находится вне пределов видимости. Было бы очень здорово! Заранее благодарю за ответ.
Hi I regularly watch your videos on RUclips. They're really helpful. Needed a small favour Can I get Arduino code for sending sensor data from Node mcu to mit android app through WiFi - WiFi communication Thanks!
I have a doubt... If we create an app to open the webpage hosted by ESP8266(eg:loading the IP 192.168.43.256) in a browser using webview, do we need to code each button to redirect ,like in your case , to move left, when left button is clicked, redirect to "IP/left".
Hey, I have a very important question. I am receiving the URL this way: if (req.indexOf("/on") != -1) { Serial.println("Turn on"); digitalWrite(relay,HIGH); } It works fine and everything, but how can I SEND data from the arduino/esp8266/nodemcu TO the smartphone???
Thank you so much Sir. You really helped me out :)
très merci beaucoup pour cette vidéo

Best video ever.

thank you this was so helpfull to me
I have a doubt...
If we create an app to open the webpage hosted by ESP8266(eg:loading the IP 192.168.43.256) in a browser using webview,
do we need to code each button to redirect ,like in your case , to move left, when left button is clicked, redirect to "IP/left".
yes

Thank you
How did you find the IP address of the nodemcu?
very nice work. very very useful for me thanks dear. good work
thank u bro...
I hope you make a reaction and a comment about what you think a live performance of Elisa in halleluja 2016.
Hey, I have a very important question.
I am receiving the URL this way: if (req.indexOf("/on") != -1)

It works fine and everything, but how can I SEND data from the arduino/esp8266/nodemcu TO the smartphone???
string method bro

@@Knowled Thanks!!!
hey can you share me code. this URL is not opening.
if i want to send data back from esp8266 to MIT app (like distance sensor). How can i do that??
use iot method

plese can you help me how to use it with a bleutooth module what shoudl i change !!!!!! thansks i w'd be grateful man !
Wait I update another video .....soon....
Thank you sir
I am staying by tuned
❤️ All love for you
Keep it up !
I am staying tuned*
how about enter ip address
Nice
Code not available
hiii.. buttom start????
no need start button up,down button act as start button
I need Access Point code and app , Can you help me ? .. thank you so much
watch my blogs
but i could'nt find the rest of the video when it will be connected to the car by wifi ! can you help me with that plz ?
Yes how can help you... Tell me ur problem...
ok ok will try .....
