IMPORTANT NOTE (18/6/2022): Seen at 4:33, the AT command for checking UART/Baud Rate on your ESP8266 ESP-01 only appears to work if the module is flashed with SDK 2.x or above. In other words, if your module has the older 1.3.0 SDK the 'AT+UART?' command will simply give an 'ERROR' message on the serial monitor. However, you can still set the UART/Baud Rate using 'AT+UART=38400,8,1,0,1' regardless of which SDK your module has. If you're not sure which SDK version your ESP8266 ESP-01 module has, simply type 'AT+GMR' in the Serial Monitor and it will tell you.
Thanks Paul so much. Off all the explanations on youtube, I think this is THE BEST AND MOST THOROUGH explanation of IoT (Arduino and Blynk) in the hobby version which can also serve serious professionals. :) Well done
OMG The Best Video updated that ever seen about Blynk IOT and Cloud. I'm from Colombia and I really enjoy your video, because I'm trying to configure my Arduino ONE Rev 3 by serial port (USB), so now with this new version I can't configure it as well as you with the esp-01. If you have some informetion about USB configuration and how to do it now, I will Thanks You! I subscribed
Hello Paul, just want to say Thank you for your Excellent Video you made, it is the best ever in the RUclips and all, A to Z information and guidance, Thanks once again, Good Luck.
I'm repeatedly facing issue while installing ESP8266_Lib.h, i've tried to install these versions (v1.0.1 / v1.1.0 / v0.6.1 / v1.3.2) but facing same issues, ard IDE showing error "ESP8266_Lib.h" no file or dir" i tried with both ways (by adding zip lib or by copying folders which you showed in the video) but didn't succeed
Hi Paul, i like this video, i have the problem with the ESP i think... i have ESP01 500kb, is the problem? you upload a new software in side esp ? thanks
Hi, Nice informative video, Thank You. In the code you have not added any extra code to control the led such as BLYNK WRITE() functions, could you please explain how the code works. There are other tutorials showing using the example blynk edgent esp8266. Can we use the same library for arduino uno interfaced with esp8266 esp-01 module...?
Hai Paul thanks for your great video i have tried your guide through your video but it works only with mobile dashboard, the LEDS On and Off normal but when i click on the web dashboard the LEDs did not work. I found that my ESP8266 flashed with SDK version 1.5.4.1 and AT version 1.2.0.0. Could you please give advise and solution (on your video you use SDK version 3.0.5 with AT version 1.7.5) and if you dont mind please share how to up grade ESP8266 module with SDK 3.0.5 and AT 1.7.5 as you have it. Wish you all the best Paul. thanks a lot.
Hello . great video . I wanted to repeat this. I have an arduino and a sim800. I flashed the arduino. the phone connects to the computer and is controlled as you have in the video. but it doesn't work on the device. in the computer shows that the device is offline and does not connect
the your video is perfect, but i have the problem, when i open the monitor serial in the ide i see the message blynk , in the second instant i have the this Message [1532] ESP is not responding. you now whwre is the problem ? thanks
blynk:29:10: fatal error: ESP8266_Lib.h: No such file or directory #include ^~~~~~~~~~~~~~~ compilation terminated. exit status 1 ESP8266_Lib.h: No such file or directory This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. Error occur like this, which library file should i installed?
thank you so much, but I have a question please, if I used another sensor to make for example pin 8 up to turn on the LED, can I see that pin 8 LED is ON on the phone or website? ( can I turn the LED ON manually and turn it OFF using the phone? )
In brief, yes. It should be possible because of the nature of cloud computing. Whatever you do on the phone will be automatically pushed to the web dashboard and vice versa.
I tend not to use 0 and 1 for TX and RX because, from my Arduino experience these pins need to be available or the code refuses to upload due to 0/1 being ‘in use.’
Could really use some help. Completed everything like above for my project and the ESP is not showing up in Arduino even though when i complete the AT commands its fine
can't we use the same pin for many leds if we add the "if'" and "else" in the arduino code ? for example if "button 1 ==1" digital write (red light on ) thank you
I have the problem to connecting the wifi which is the serial monitor display [703] Connecting to SYIFRAH_NICO 8467 [1759] ESP is not responding can you give the solution?
I'm using NodeMCU ESP8266 v3(ESP-12E), I configured as ESP-01 which used in your video (included AT commands) but ESP can't connect to wifi, otherwise it created own wifi. So device on Blynk cloud offline. I hope you can help me! Thank you very much.
It shouldn’t be a huge difference in terms of programming your module for AT commands. The ESP Link v1.0 just makes it far easier to connect the ESP8266 ESP-01 modules without having to use excess wires.
Hi, my esp01 worked perfectly fine... But I have only 1 problem. After the serial monitor says 'Connected to Wifi', the 'Ready (ping : ...)' doesn't appear, means that it haven't connect to blynk yet... What to do to fix it??
my question is that how to use digital pin 14,15,16 of arduino as output because in blynk there's maximum digital pin 13(from 0 to 13)is available. Plz help me
I managed to control it with my phone but the buttons on my laptop don't update. I also can press a button from my laptop, it lights up the LED but the color of the button doesn't change and after that, i can turn off the LED only from my phone. Does anybody know how can i fix this?
I don't use blync, I write my own web page. On this web page (phone or browser) I included a Refresh button. On either side, I press/click the refresh first.
As far as I understand, Blync it is updating only on demand. You'll see the actual temperature only after you operated a button. Then the value is frozen on the display.
@@jadeashten Weeell I didn’t. Eventually I gave up on the idea of connecting my mega board with esp8266. Everybody recommended to buy a wi-fi board if you’re looking to make an IoT project.
@@viktor7425 Thanks for the reply! After days of struggling, I actually did manage to fix it - it was to do with configuring the baudrate of ESP8266 with your specific wifi requirements! I agree having wifi built into the board would have been a much more efficient alternative!
So how do you wire 4 rooms from one controller, and if you did, that would cost you £6.00 perm month every month so a total of £72 per year to switch 4 lights, that is stupid!!

Good video. What needs to be done to make the program work on the ESP8266. The Uno is too big to be installed in an electro dosa. LP
it already works
thanks a lot. It was useful!!
Hey whenever you get a chance try doing a video with a arduino mega 2650 with esp8266 built in. For some reason I having issues
That was really really interesting
I'm tired with this ESP and Blynk 2.0 always connection error T_T
same
Hey Paul, well done I liked too much, simple question is it possible to access or control those LEDs over internet.?
Thanks a lot! The answer is yes, you can control them over the internet.
@PaulMarriott so you mean if im not connected to same wifi that esp01 is connected to , then too it would work? It would work on mobile data too?
Thanks, it worked 🤩

ESP is not responding, please anyone help.Thank you😢
is there 2 Arduino programs? one for the arduino uno and one for the wifi module? I am a little confused lol
No, the main code is just for the Arduino Uno. As for the ESP-01 module, you only need to ensure the baud rate is set to 38400,8,1,0,1.
Why do I keep showing invalid Auth code in serial after uploading
what firmware are you using at that esp?

Hi, just want to ask it is possible to access the 4 leds also with push buttons?
what can i make if my esp is not responding? thank you
is it possible to use a servomotor? i want to control a servo with the blynk app and a thermometer.
if i don't have the esp link , can i just use the esp01 with 115200 baud instead of 38400 ?
Yes for me it worked
any thing write in the serial monitor keeps give ERROR
any thing to help ?
