please Make a project on "ARDUINO UNO with ESP8266 & 8 CHANNEL RELAYS" and program it..... 🙏🙏🙏🙏🙏
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!
"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 :)
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.
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
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 think this is the best tutorial for Arduino to EPS without AT command manually
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......
after hard days, at last find a really working tutorial. thank you bro :)
Thank you. Clear, concise and to the point.
thank u man your video crystal clear teaches the esp connection and finally its running a big thanks
Thank you so much for your video. Waiting for more ESP8266 videos
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.
So by doing this process, do you connect the Arduino Uno to the Wi-Fi?
can i use the RX and TX pins for communication as well?
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!
thanks a lot sir, u have really helped me , i was struggling helplessly up until i came across this video............
When connecting arduino reset to gnd, n attempting to upload the code to esp8266, "could not open port COM7" error is coming
and how can I connect the ESP to the WLAN?
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
How can i do. If esp01 returns a string for example if esp01 returns led_on , uno lights the led up
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?
Yeah, tomorrow i'm gonna make this. Thanks for sharing this piece of tutorial. I'm a newbie :) Thanks!
Thanks so much for the tutorial have had a hard time trying to get it to work.
Can i use the 3.3V from arduino directly....without using the voltage regulator?
Uno with ESP-01 (SoftwareSerial) on connecting to Firebase ?
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!
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?
i would like to connect a similar project with google firebase. is the procedure similar?
do i need to connect both arduino and esp usb to computer?
It is also possible to have the two controllers connected to different power supplies isn't it?
Please can you tell me how to get and install software serial library. Thnx
Hi :) can i use this connection to flash AT commands?
Can I use esp8266 together with Hc05 bluetooh module using 1 arduino uno board
Uploading this sketch on ESP, does the firmware erase?
help me sir, i have done everything but nothing is being printed in serial monitor after uploading to arduino
i have a probelm ... the StringReady in arduino code never seems to get true for me ... i couldnt figure out y
my arduino in serial monitor does not show any strings from the esp. it shows only Received String: How can i fix this?
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
Which operating system are you using?
Is possible to send and receive serial data between ESP-01 and Arduino UNO in same time.
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
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.
is it neccesary to use voltage regulator
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 ?
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 😭💔
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...
Shurkiya. Best tutorial for esp8266.
Best video seem explaining esp8266 + arduino
Is it important to flash firmware in esp01
So i need to upload code to esp01?
Thank you my friend and i want to send data from Arduino board to esp-01 please tell me if you knows
why did you use software serial ? you could have left in on de hardware serial ports .. or is it a must ?
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
Amazing tutorial!! Thank you so much
I can't download the part in preferences
Why i cant reset the esp-01 after doing this ?
Can you please give schematic if using breadboard power supply instead of regulator ?
Sir esp-01 gets disconnected from wifi after few seconds. Can you please help me.
Man you are awesome. This was really useful.
Great tutorial from great teacher. It is a pity that there is no much tutorials about Arduino
I will to add more. Thanks.
Hello! what if my port is not clickable?
Dude, that's a great tutorial, tnks for sharing.
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.
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
thanks for this awesome tutorial.
Excellent video. I saw this first time and have subscribed your channel.
Thanks.
Great explanation, thank you.
What if we connect rx to tx and tx to rx?
Helped me resolve upload_mem error
wow, the video has some audio problems, but the content and code it's great, thanks for sharing
This is best out there. The others are really not for beginners.
An awesome video. Congratz
Nice Tutorial, Thanks for sharing this.
thank you very much, this is the most complete tutorial
I can't communicate using software serial. Whyy? Help me please
do you know how to send data from arduino to esp-01?, great video c:
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!:)
My adruino is only receiving data if i disconnect the pin 2 for a very short time. Anyone encountered this problem before?
it is very good video can you explain how to send sensor data from arduino to esp and from esp to webserver or thingspeak
Why you dont use 3.3 v direct
how to connect two channel relay board with two light bulb, esp8266 wifi module and arduino uno
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
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.
Fantastic tutorial!
thank you! it finally works
mine is esp8266 esp01s, is it the same to this? can my procedure be as same as yours?
yes.
When uploading on ESP8266 I am getting message :Hard resetting via RTS pin... what to do please suggest
Please recheck your connections. Especially TX, RX and reset pin from Arduino board. Do check if there is any loose connection. Hope you are using 3.3v regulator as suggested.
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
thanks for the tutorial.. but i have some problem that my serial monitor received some messages not "Hello from ESP" but sometimes "Hel F?Rm ESP" "He??e ESP" etc.. why?
Please make sure that baudrate is same in both arduino and esp
thank you for your help, I subscribed
thanks a lot for tutorial !
Getting this error, some one help.
esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header
did u find any solution?
im having trouble with the first part. when i try to upload the first code, i get an error saying, "stk500_getsync() attempt 1 of 10: not in sync: resp=0x00" i've tried reseting the board and also unplugging. any suggestions??
Please check if your schematic is correct. May be try swapping TX and RX. If nothing works, please share the picture of your schematic.
Change the board to ESP8266Module.
will you please guide me for my project
Hello I have connected as per the circuit shown please comment why i am getting below error
