Yo after a billion youtube tutorials, this is the only one video where I have been able to get the ESP8266 to actually do something! Thank you so much man! :DDDD
@Random Duo I guess you already know this. For the rest : Changing baud rate to appropriate one will show the correct message.
"Connect the Reset pin of the Arduino to ground" for the WIN!!! THANK YOU! :)
This was the straight forward tutorial I was looking for! Once the 3.3v regulated is powering the esp8266, its digital output are still recognized by the 5v arduino inputs. However, in a perfect world I would use a voltage divider to lower the digital output from the arduino to esp @ 3.3v. OK, Im going to try. Thanks you :)
You're probably the only one (I watched) so far that explained how to connect ESP-01 and Uno (Nano perhaps), nice and good job friend.
I wasted a lot of time looking through written tutorials and nothing really got to what I was looking for. This was great. I finally have a telnet server that I can use to communicate with an arduino remotely!
I think this is the best tutorial for Arduino to EPS without AT command manually
I found this tutorial after 3 hours of trying to figure out why mine wasn’t working, I just went into run app data and deleted the old eps8266 folder I had and then re downloaded the same version he used and it magically started working!!! Thx so much
Thank you very much.
I have been searching for a couple of weeks, and your video is the ONLY one that gave a complete solution; meaning covering the programming stages (code + connections) on BOTH ESP2866 and Arduino!
Best regards.
After finding so much on internet i found it ..... your explanation is nice with proper details with ( do, don't do and why don't do)...thank you......
Outstanding tutorial! You don't miss a single detail. I followed these steps and everything worked perfectly. Much appreciated.
Also, I did this without the 3.3 Voltage regulator although I haven't done any long term testing.
What did u use instead of the regulator ?
how?! without voltage distribution
Thanks for mentioning about the voltage regulator ... I would have used the onboard 3.3v ... after investigating the uno and Mega2560 they both only supply 50mA ... The esp8266-01 can use as much as 170mA during transmit. I will probably try it with 2 - AA batteries ... only 3v but i am guessing it will still work fine.
You are really great man......Thank you so much... I thought my esp01 was dead...but turns out that I didn't knew to use it correctly. Thank you so much
Glad I could help!
and how can I connect the ESP to the WLAN?
after hard days, at last find a really working tutorial. thank you bro :)
Thank you. Clear, concise and to the point.
it is very good video can you explain how to send sensor data from arduino to esp and from esp to webserver or thingspeak
Great tutorial from great teacher. It is a pity that there is no much tutorials about Arduino
I will to add more. Thanks.
thank u man your video crystal clear teaches the esp connection and finally its running a big thanks
Best video seem explaining esp8266 + arduino
Shurkiya. Best tutorial for esp8266.
Excellent video. I saw this first time and have subscribed your channel.
Thanks.
So by doing this process, do you connect the Arduino Uno to the Wi-Fi?
wow, the video has some audio problems, but the content and code it's great, thanks for sharing
thanks a lot sir, u have really helped me , i was struggling helplessly up until i came across this video............
Dude, that's a great tutorial, tnks for sharing.
Yeah, tomorrow i'm gonna make this. Thanks for sharing this piece of tutorial. I'm a newbie :) Thanks!
Thank you so much for your video. Waiting for more ESP8266 videos
Instead of using the reset pin at the beginning to bypass Arduino UNO can it also work by removing the ATmega chip of Arduino?
Few things to consider:
1) Removing/Putting IC Chip might break pin of the chip(If done carelessly). Hence RST Pin Bypass is easy method.
2) There is also SMD Version of Uno (www.flipkart.com/adraxx-arduino-uno-r3-compatible-atmega328p-development-board-smd-version-cable/p/itmfybz4fugrvmpf)
Amazing tutorial!! Thank you so much
do i need to connect both arduino and esp usb to computer?
why did you use software serial ? you could have left in on de hardware serial ports .. or is it a must ?
This is best out there. The others are really not for beginners.
thank you very much, this is the most complete tutorial
In some tutorials i saw that u need to connect esp rx to tx of the arduino, when u go rx to rx and when rx to tx ?
to program esp8266 he is using RX->RX and TX->TX and for listening or serial communication he is using RX->TX and TX->RX.. this is what i understand correct me if i m wrong
Oh so once the esp8266 is coded, it will automatically do it when connect to arduino? So how do I code so that the esp8266 automatically connects to my wifi
use the esp8266wifi library and esp8266httpclient library
thank you! it finally works
Fantastic tutorial!
Hi, I'm getting an error
esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header
What could be the reason?
urgent!
Flow this steps "
1- Open Serial Monitor
2- make GPIO0 inside ESP8266 To Ground
3- Reset Module by power on/off or by putting RESET Pin to GND Once and disconnected again
4- if previous steps is success u must see some string in serial monitor that mean ur module in programming mode and ready for uploading code to it
5- upload sketch and have fun
6- if u want to test ur sketch then swap module to normal mode by disconnect GPIO0 from GND
7- reset module as step #3 after that module will work in normal mode and execute ur code
@@Omar.bin.khattab Appreciate your inputs. I had the same issue and your fix helped me to resolve this.
@@sunnybera1327 happy to hear that ... have a nice day
Error: The selected serial port_does not exist or your board is not connected.
What should I do ?
🙏
Change the ports , from Tool > Port > u may be shown many , well one of them works ...... Try all of them one by one
very good my friend, good job
I am getting this error , I am using without regulator and using 3.3 v. raise FatalError('Failed to connect to %s: %s' % (self.CHIP_NAME, last_error))
esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header the selected serial port does not exist or your board is not connected. Can you please help ?
sir i have a major question, can i do this vice versa ? i mean instead of ESP module are sending/writing ? arduino uno will send or write data/string and esp will catch or get the data ? is that possible ? if it is how can i do it ? sir i'm having a bit problem with it, a reply would be appreciated sir.
Well, I did not try this but try following. As per the tutorial, we are reading a string in Arduino and writing a string from ESP. Do the vice-versa. Since, we are using SoftwareSerial library for Arduino, refer to following link to be used in Arduino. www.arduino.cc/en/Reference/SoftwareSerialWrite
For ESP Code, you can simply write, Serial.read....Try this out and please share your findings. If it does not work for you, I will try it in my free time. Hope this helps.
Nice explanation thanx
Thanks so much for the tutorial have had a hard time trying to get it to work.
perfect tutorials ..... can u make another one for making module run as Web Server and how to communicate to Arduino as web server .. thanks again
Great explanation, thank you.
Sir esp-01 gets disconnected from wifi after few seconds. Can you please help me.
Realy a working tutorial
Can i use the 3.3V from arduino directly....without using the voltage regulator?
Nice Tutorial, Thanks for sharing this.
Is possible to send and receive serial data between ESP-01 and Arduino UNO in same time.
thank you for your help, I subscribed
Can I use esp8266 together with Hc05 bluetooh module using 1 arduino uno board
Sir i try this on esp o1 and uno it is working perfect but when i trying on Arduino mega 2560 it show nothing on serial monitor with all communication pins what i can do?
HI am using a loRa-02 radio module and it also communicating with my Arduino and everything goes well until I add mySerial(2,3) then nothing show's up, help please!
how did you have the virtual serial com port? I can't do it cause I have only one com port
How can i do. If esp01 returns a string for example if esp01 returns led_on , uno lights the led up
Thank you my friend👌
I also ran into the 'Times out waiting for packet header' error. Only after using my first Arduino board (lolon d1 mini v3.1.0) for not even an hour. I am a beginner and I don't understand the troubleshooting process and the comments so far on this problem still leave me clueless how to proceed. I have another board, but I have no idea why it got bricked so easily so I don't want to try that one now.
Can it be restored without doing hardware stuff? Just by connecting it with the USB? Any help is greatly appreciated.
thanks for your knowledge sharing
So i need to upload code to esp01?
Uploading this sketch on ESP, does the firmware erase?
thanks man u r legend
Liked and Subd. A quick question, why did you move tx/Rx to pins 2&3? Could you have left them as is? Awesome and very descriptive video!
Unsubscribe and unliked,
@@lasthandman are you talking to yourself ? hahaha
Excellent Video!
I would like to know how can i read the data from my equipment and transmit it back to it me on my smartphone.
Let say I have an inverter for my solar panels and everytime i have to go physically near to it and check can i get the same values on my cell phone using this method.
Yes my inverter have a rs232 port
If you could read values from inverter and send it using MQTT, you can receive it on your smartphone. Please check my MQTT videos. It's part of my new series "Alexa based smart light"
Why i cant reset the esp-01 after doing this ?
mine is esp8266 esp01s, is it the same to this? can my procedure be as same as yours?
yes.
Do you have idea about Esp8266 wifi module? I have a problem. AT Commands doesn't work. It only displays reversed "question marks". Thank you again
thanks, it helped alot
hey bro i have arduino uno along with temp,humidity,soil moisture,rain sensors. and i want to save these values into my website domain's database. can u help me how to solve my problem. how can i fetch all readings from Arduino uno to NODEMCU esp8266. then pass these values to DB
Why haven't you level shifted tx & rx channel btw 8266 and uno?
As per data sheet 8266 tx and rx are 3.3v reff
i would like to connect a similar project with google firebase. is the procedure similar?
can i use the RX and TX pins for communication as well?
i have a probelm ... the StringReady in arduino code never seems to get true for me ... i couldnt figure out y
Sir if I want to get values from arduino to esp01 than how i can do.?
DID YOU FIND THE SOLUTION ?
my arduino in serial monitor does not show any strings from the esp. it shows only Received String: How can i fix this?
Can you please help me out? I have a different ESP8266 module which has different configuration and pins. I'm unable to find a VCC pin. Can you please help me out?
i m getting "espcomm_failed" error...also why didnt u use 3.3v directly from the arduino?
Rasheed, I have explained why not to use 3.3v directly. Use it the way, I have explained and it will work. Please check the wiring again as well.
You have got good teaching video. Thank you! But would you help me in similar case - I have got ESP-01 adapter, where I can plug my ESP8266. It has 8 pin connector and out I get 4 pins - VDD, GND, RX, TX. I would like to control, for example, a LED with Mobile phone. So I need to connect it somehow to Arduino (which I can maybe figure out myself), then I need some S/W to connect with my mobile phone to me ESP8266 (like to Bluetooth HC-06 module), which I believe I can find in Internet, but how about Arduino code? How to program Arduino to receive signals and to operate LED?
Thank you in advance!
BR,
Valters
I would recommend to use ESP8266 Dev Board + LED + Mobile to achieve what you are looking for and skip Arduino. The reason I am saying that is you could achieve what you want without Arduino. For some specific reasons, if you wish to use Arduino then you have following choices: 1. Use combination of Arduino + LED + Mobile + Bluetooth module and control LED from your mobile using bluetooth. In this case, you don't need to use ESP-01 2. Let's say you wish to control throught WiFi. Then use Arduino + ESP-01 + LED + Mobile + MQTT (CloudMQTT). Mobile will send the on/off request to MQTT. You can download an existing MQTT app for mobile. ESP-01 will be a subscriber for MQTT. As soon as, mobile sends the on/off request to MQTT, ESP being a subscriber will receive the same. Next, ESP will pass on the on/off request to Arduino through serial communication and Arduino will turn the LED on/off basis on the instructions it has received. Further, in option 2, you can still choose to skip Arduino, ESP-01 and use ESP8266 dev board instead. Personally, I would prefer to use serial communication where something is already designed using Arduino and I need to extend the functionality using ESP. For example: Let's say an arduino based car is already designed and now I want to control it using Alexa voice commands. In this scenario, I will add ESP-01 on top of Arduino. Hope this helps.
sir, great tutorial.. hats off to you.. sir, i have a question though, id be really grateful if you answer my doubt.. When, we upload the code to esp, does that mean we have- flashed the firmware and uploaded a new firmware (which is our code) , or is the original firware still there along with the program that we have just uploaded (to the esp)..
help me sir, i have done everything but nothing is being printed in serial monitor after uploading to arduino
do you know how to send data from arduino to esp-01?, great video c:
An awesome video. Congratz
I only have 1 port that is COM5(Arduino/Genuino Uno), is this the right port or should there be 2 ports?
That's the right port man!:)
good explaination bruh... btw i have question need to be ask. do you know how to make doorbell able to send signal to camera to snap a picture after the doorbell being pressed?
This can be achieved in multiple ways. Place a motion sensor/ distance measuring sensor (ultrasonic)/ touch sensor with door bell and send the signal through bluetooth or MQTT to the Raspberry pi. On receiving the signal, Raspberry pi could execute the command to click the picture. If you are using a foscam, check for foscam APIs. They also provide this feature for developers.
In My case It is showing an Error: "Failed to connect " Even the connections are same as in the video.. plzz help me to resolve this issue.
It is also possible to have the two controllers connected to different power supplies isn't it?
You could directly receive 3.3 volt from arduino board and u did not need to use a voltage regulator
I think you could but in my case, the Arduino Mega only supplies 150ma, where as the esp8266 v1 I have maxes out at 250ma
Bro i try to run GSM module on Generic ESP module board in Arduino .. but the software serial of the GSM is not running on this board .. what is the solution? please help me .. i search about this a lot of time really 😭💔
I can't communicate using software serial. Whyy? Help me please
You connect ESP uart (3 Volts !) directly to Arduino Uno uart (5 Volts!) ??? Are you OK?
ESP may be damaged!

1- Arduino ground
2- 3.3v output (+)
3- 5v from arduino
My adruino is only receiving data if i disconnect the pin 2 for a very short time. Anyone encountered this problem before?
thanks for this awesome tutorial.
