thank you for explaining to me like a child. :) this is how explanations should be.
One of the best video for ESP 8266. Such detailed explanation ... :)
Thanks a ton
Thanks indeed, you have presented a full detail explanatory course. Very helpfull!
You are welcome. I am glad you liked. Salamat bashi.
Excellent. I've been doing Arduino with you for sometime, I have a good understanding of it and the ESP family seems to be the next move.
Wonderful video, thanks!
Best esp8266 video on TH-cam❤️
Great video, thanks for sharing.
a very underrated channel. you deserve moreeeeee
Thank you. I have patience. Let's see.
very well explained as usual I learned a lot from being subscribed to your channel. thank you
Great to hear!
The most useful video for ESP8266 a beginner user, very helpful. Unfortunately i see the code 301 today May 2022 but i'm very happy that meet your channel!
Same not sure how to fix the issue
where/when do you see code 200? I have not encountered that.
I don't get code 200, it write code 301 instead and says that its redirected.
But luckily i can connect my Esp8266 with our WiFi router
@@rickyoh4386 me too
GREAT ESP32 INFO.. i am just getting started to learn about this little module and with kicad this should open up to lots and lots of neat ideas... thanks a lot...:)
ooops esp8266...:/
I am glad you liked it. You could edit your comment by clicking on the 3 dots.
this is nice video for me start learning Ncu esp8266
great thz
bunu bildiğim iyi oldu. abone olmayı unutmayın. Teşekkürler Ahmed Horasan'dan
thanks for the video, I have an ESP-12f board, I have programmed, and now I cannot get it to accept flash anymore. It still works.. but I cannot seem to get all the conditions to flash. Can you suggest how to troubleshoot not being able to flash?
Good video, thank you.
Thank u learnt alot
Nice explanation!!!!
Thank you.
Is this out dated information as you are using 1.8.9 and has the library changed now the ESP8266 is 2.7.4
Great video.. you get my like and subscription..
Thanks. I am pleased you liked it.
ماشالله بسیار عالی موفق باشید انشالله
salamat bashi.
ma sha ALLAH , NICE VIDEO!
shukran akhi.
do not see the esp8266 file indicated in the video under file manager (other options)?
Great Sir....👌👌👌👌
thanks.
Thank you
You are welcome. The best thank you for me is to subscribe to my channel. Thank you.
I got http code 301 with my esp8266 even when I tried uploading the BasicHttpClient sketch to the device. Any ideas how to solve it?
👌👌👌👌👌👌
😊
Great video - I have not a clue what I'm doing here with C - however couldn't get code to run - stated char type="k" was wrong (complex unpermissave error and stuff I didn't understand). Changed it to String type ="k" and works perfectly. I have no idea why!
Hello and thank you. you must have customized the the code. The code posted after demonstration and it should work. please try using it first without any change, then make changes.
@@robojax thanks for the reply - I had inadvertently ‘customised’ the code in at least 7 places, having fixed my own errors I still couldn’t get that bit to work. Pasted the error message in and found out far too much about char* constant errors. I never coded in C in my life, just a hobbyist - playing for fun really. But changing ‘char’ to ‘String’ made it work with j. Then I put the k in and it didn’t. Being irritated by then I just uploaded it again (which is clearly stupid and should not have worked), but, it did. I saved it quickly!
Many thanks for your reply though, most kind, I shall watch more. :) Phil
you are very welcome. stay safe.
Hey robojax, are you in the Toronto area by chance? I'm working on a project and would really appreciate a little bit of guidance.
Hi, I am in Ajax but busy with my full time job in a University. Beside spending working on TH-cam videos, I have got no time. Sorry.
@@robojax I understand. Thank you for the reply.
So essentially you have a remote 8622, taking a temperature, and acting as a website that can be accessed by a PC- browser to display the data in nicely- formatted form; correct?
Just getting started so thank you!
Yes indeed.

Excellent video, very helpful
I am glad you found it useful.
Can you read data simultaneous from more than one sensor with this Node MCU ESP 8266 and transmit them via WiFi? Thanks!
Yes you can.
I guess you will not tell me how...:(
It needs 10 to 20 minuets video to explain. But your question was "can" and I said yet. I am replying to 1000s of comments. Can't write paragraph unless absolutely needed.
@@robojax I know and Thanks for answering! I just thought you will guide me a little...like: ”if you use digital sensors you do that...if you use analog sensors, you need that...”...or to guide me to some video that i didn't manage to find...
Sir can you please make a video of reading ADXL345 accelerometer sensor using enodemcu 0.1, it would be
a great help,
Thanks in advance
I have got the module, but no time. God willing, when I will make video for that.
Very good explanation!
Any idea of how we could use HTTPS instead of HTTP?
You're just changing the url used I presume? Like any website you would use.
I need your help to do the "HTTP server which is waiting for HTTP Post request. These requests then proceed with string masks and parameters for LED and Display control are flirting. Then ESP turns on / off a certain LED and shows a number or string on Display.
please help with how to start with.
I wish I could help. your request involves lots of understand and testing which can't be done by few line of comment.
@@robojax Thanks
Can you make it work wirh 3.3v vin?
why my ESP8266 does not appear on my port? All I have was COM 1 when I connect it tot he USB port it does not show any other COM port?
because you don't hae the drivers for it. check the chip (with magnifying glass) it must be CH340. if so check the video I have for Arduino which has the same USB chip th-cam.com/video/u_21yNqd03I/w-d-xo.html if it is CP2101, then windows recognizes it. or your USB cable is bad. try another cable.
can I programing that node MCU without arduino IDE ? ?
Yes using python if you learn it
بسیار زیاد تشکر
سلامت باشید.
بسیار خوش شدم بخیالم که وطندار ما هستی

Sir, if nodemcu is fitted in box then what to do so it will not be overheated
sorry, didn't understand. which box?
@@robojax I mean in Packing with small air vents
make holes like 3mm holes 4 holes at top and 4 at the bottom of the box and that would be enough.
Thanks for ur nice video, are u from ifan?

Do you work in embedded system field?
@@robojax At the moment, I am doing my internship, I am mostly working with esp32.
How is the job opportunities in this field in Canada?
مشبخشید متن نظر شما ندیدیم زیرا من تما نظریات (کامنت) همه ویدیو ها را در یک صفحه میبینم این باعث شد در طول صفحه از نظر غایب بماند.
بلی همه هموطن هستیم و همزبان. من خراسانی هستم. از خراسان بزرگ که شامل تاجیکستان ، بخارا و سمرقتند و افغانستان امروزی و شرق ایران. امروز تنها در ایران یک منطقه چک یاد اورد آن خراسان بزرگ است. بر اساس تقسمیان جغرافیایی امروز من افغانستانی هستم. اما فارسی اکثریت مطلق مردم افغانستان فاارسی زبا اند و یکعده هم اوغان ( افغان که آب را او میگویند افغان را اوغان میگویند) و تقریبا 150 سال و اندی قبل اسم خراسان را افغانستان گذاشتند و انگلیسها در این فاجعه نقش داشنتد.
به هر صورت خودت عزیز هستی برایم و موفق باشید.
The best way to test the job market (not in COVID-19 era) is to check on Indeed.ca and post a resume or search for "embedded systems" or other keywords. I am not sure. I work at a University and am involved with technical support and labs and helping Engineering Students. I am Electrical Engineer with years of experience in Programming.
What is happens when ams1117 (voltage regulator) is shorted?
it depends on which pins. if input and output are short circuited, then the 5V input go to the output pin and reach ESP8266 chip and kills it.
@@robojax It happens to me, but the input is about 1v, and the output is 0v. Before it, the smoke has flown out from it. What about protection of the circuit based on datasheet of ams1117?
there is no protection. ESP8266 has not protection. when voltage goes higher than 3.3V, perhaps 0.5V higher, it might tolerated for half a second and then it dies.
I don't get option to select the port\com what should I do? I get many errors
Install the driver. hC340 or something then this driver will work th-cam.com/video/u_21yNqd03I/w-d-xo.html
Did you resolve the issue?
could you possibly put a link into the comments on where i can download the program that you use
The link is under the video in description
@@robojax oh yeah sorry
May be I did not get what you said "Where I can downlaod the program? there is the code I used. Then I used the code inside the Arduino IDE program which you can get from Arduino.cc website. The code is and resources is under the video in the description. Here is how you find it snipboard.io/gplc41.jpg
if you want to learn about Arduino IDE software, I have a full Arduino course. The link is in the description of this video.
It's shows an error when I go to Boards.Esp8266 not added
Sir help me
share the error.

How can i connect my nodemcu to office wifi? My office wifi need to login first via browser.
no you can't. you must have SSID and password.
Ahmed engineer. Peace be upon you I used nod mcu with sinrik site with wifi manager every time i show my error message de class WiFiManager' has no member named 'addAP'
I hope to know what
Peace b upon you, have you prepared your Arduino IDE for EXP8266? it seems files missing.
@@robojax Yes, I have entered all the libraries for WIFI MANAGER and ESP8266 settings
then you might not have selected the right board.
@@robojax I thank you, dear brother. I will discuss the subject, and I need time to thank you very much
I cant get this to work what libary did you use.
Add the drivers the way shown in video
Sir how to reset the program and program another program to that board
What do you mean reset? I have just shown the blink . Do the same, open the new sketch and upload it to this module. simple as that.
@@robojax no bro after upload the program I may create and upload the program then how I reset that program can you say about it
thanks, can you share html or .php code please...
You are welcome. PHP CODE is added to the code page. the link is in the description of the video and here again robojax.com/L/?id=249
@@robojax ok but the code in your page is linked to another php running back...

So kind of you. thank you.
Got it to its talking to server and comming back with coad 200 but then you lost me.
Hello, as the title says this is "introduction" so I could not convert. when you use HTTP client it is like typing an address in browser. it just types and requests. that is first. then if your server responds (or the page opens in browser) with JSON, this MCU can understand it. as simple as that. the rest is your job or the server job how to use the data.
I have Windows 7, i dont have ports...
windows can not be without ports. Port means all input and output of your computer. When you connect a device to usb, that make a port.
yeah sorry to bother you again so soon but i was actually unable to find it in all that
im really sorry
Unable to find what? You didn’t find the description of the video or the links inside the description?
This is terrible, you don't show any of the code anywhere for the http GET request.
It is hard to please everyone and show example of everything. I have tones of tutorials. here is one that you can send request to server to control motor th-cam.com/video/OZ0kaZmmW2I/w-d-xo.html
