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.
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!
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.
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 :)
I think this is the best tutorial for Arduino to EPS without AT command manually
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 hard days, at last find a really working tutorial. thank you bro :)
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......
Thank you. Clear, concise and to the point.
thanks a lot sir, u have really helped me , i was struggling helplessly up until i came across this video............
thank u man your video crystal clear teaches the esp connection and finally its running a big thanks
Best video seem explaining esp8266 + arduino
"Connect the Reset pin of the Arduino to ground" for the WIN!!! THANK YOU! :)
Thanks so much for the tutorial have had a hard time trying to get it to work.
Thank you so much for your video. Waiting for more ESP8266 videos
Shurkiya. Best tutorial for esp8266.
Yeah, tomorrow i'm gonna make this. Thanks for sharing this piece of tutorial. I'm a newbie :) Thanks!
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
This is best out there. The others are really not for beginners.
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
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!
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 ?
thank you very much, this is the most complete tutorial
Dude, that's a great tutorial, tnks for sharing.
Amazing tutorial!! Thank you so much
Great explanation, thank you.
wow, the video has some audio problems, but the content and code it's great, thanks for sharing
thank you! it finally works
Fantastic tutorial!
Nice Tutorial, Thanks for sharing this.
Man you are awesome. This was really useful.
thanks for this awesome tutorial.
An awesome video. Congratz
Great tutorial from great teacher. It is a pity that there is no much tutorials about Arduino
I will to add more. Thanks.
Interesting. Thank you.
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.
Excellent video. I saw this first time and have subscribed your channel.
Thanks.
it is very good video can you explain how to send sensor data from arduino to esp and from esp to webserver or thingspeak
thanks man u r legend
thanks a lot for tutorial !
Nice explanation thanx
Realy a working tutorial
it does work thanks
Thank you my friend👌
and how can I connect the ESP to the WLAN?
thanks for your knowledge sharing
thank you for your help, I subscribed
can i use the RX and TX pins for communication as well?
thanks, it helped alot
do you know how to send data from arduino to esp-01?, great video c:
Thank you my friend and i want to send data from Arduino board to esp-01 please tell me if you knows
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.
Please can you tell me how to get and install software serial library. Thnx
how did you have the virtual serial com port? I can't do it cause I have only one com port
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
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 would like to connect a similar project with google firebase. is the procedure similar?
Can i use the 3.3V from arduino directly....without using the voltage regulator?
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!
It is also possible to have the two controllers connected to different power supplies isn't it?
Thank you so much!!!!
So by doing this process, do you connect the Arduino Uno to the Wi-Fi?
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 haven't you level shifted tx & rx channel btw 8266 and uno?
As per data sheet 8266 tx and rx are 3.3v reff
How can i do. If esp01 returns a string for example if esp01 returns led_on , uno lights the led up
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
do i need to connect both arduino and esp usb to computer?
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
Awesome.
Hi :) can i use this connection to flash AT commands?
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.
Can I use esp8266 together with Hc05 bluetooh module using 1 arduino uno board
why did you use software serial ? you could have left in on de hardware serial ports .. or is it a must ?
Uno with ESP-01 (SoftwareSerial) on connecting to Firebase ?
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
Is possible to send and receive serial data between ESP-01 and Arduino UNO in same time.
is it neccesary to use voltage regulator
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.
i love u boy
Can you please give schematic if using breadboard power supply instead of regulator ?
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?
How to get esp wifi details and ip address...
I want to use it for RFID attendance syaytem with RFID+Arduino uno+esp wifi so that all data from RFID should come on php database...
Plz sir help regarding this I will be very thankful...
Which operating system are you using?
When connecting arduino reset to gnd, n attempting to upload the code to esp8266, "could not open port COM7" error is coming
Uploading this sketch on ESP, does the firmware erase?
Sir Thank You
my arduino in serial monitor does not show any strings from the esp. it shows only Received String: How can i fix this?
help me sir, i have done everything but nothing is being printed in serial monitor after uploading to arduino
Thank you man! You save me hehe 😁
LD1117v33 noting it down for my reference.
1- Arduino ground
2- 3.3v output (+)
3- 5v from arduino
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 ?
Is it important to flash firmware in esp01
thanks for ur efforts sir.... can i directly connect nodemcu with uno with regulators??
I believe your question is, "Can I connect nodemcu with UNO WITHOUT regulator ?" Here, I am assuming that when you are saying..."NodeMCU", you mean ESP-01 board and not the NodeMCU development board. Assuming that my assumption is correct, answer is...if you are lucky, it would work for you. You need to use 3.3 v from UNO instead of 5v and rest of the process would remain same. The challenge you would face is to upload code on ESP-01. If it does not work, you would keep struggling for hours. Though if you use 3.3v regulator, it would surely run for you. So, my vote is with using regultor. Though you can still give it a try. Don't attempt to use 5v directly with your ESP-01. It may destroy your ESP. Hope this helps.
ArduinoThing thank you very much for your precious time and attention sir. i will definitely try this out
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!:)
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 😭💔
So i need to upload code to esp01?
Great video - thanks. Until last 20 seconds. Error opening serial port COM5 . port busy. is the esp using that port from the first section of the video? Any help welcomed.
Please try following the video from 8.40. Also, try unplugging arduino board from your computer and replug it.
Also do check TX RX wires. You might need to swap.
i have a probelm ... the StringReady in arduino code never seems to get true for me ... i couldnt figure out y
After programming the esp8266, you change tx and rx of it to pin 2 and 3 of Arduino directly. I have seen other video where people pass it through a logic level converter. Is that necessary or can I do it the way you have done.
It generally does not matter and ESP-01 works properly. Though it would be a good idea to pass it through a logic level converter. Thanks.
@@techsteering Thanks for the prompt reply!
