2:23 install the CH340G driver
3:03 download ESP8266 file from IDE board manager
4:53 NodeMCU V3 board pinout
4:57 connecting the wires
5:24 simple code to test computer connection
6:57 connect your ESP8266 12-E board to your WiFi
We finally got a new development board, the NodeMCU ESP8266 V3 12-E board. In this video of the NodeMCU v3 tutorial, we see how to set up and connect the NodeMCU board to a computer an home wifi. We explain what ESP8266 is and how it's integrated into this board. We go into the Arduino IDE to install the ESP8266 board catalog. We then test the ESP826 board connection to the computer and see how it reacts to a simple LED blink code. Finally, we use our own SSID and password to get the NodeMCU board connected to wifi. Once we learn to setup up the NodeMCU v3 ESP8266 wifi module, we can explore this board with fun IOT projects. By connecting the ESP8266 12-E Development Board To Your Computer and Wifi, we will be able to access the board remotely.

I'm new to this kind of stuff. I'm curious if this wifi thing has any practical purpose, other than as a fun thing to tinker with. If I hooked this wifi thing up to my Surface Pro 2 would it give me more powerful internet?

@BMonsterLaboratory Рік тому

Hi Dirk Tyler! Great to hear from you. There are many practical users for this board. The board itself has remained very cheap on ebay. I have only used it for automation when using home appliances or lights. It can also be used for robotics, wifi monitoring, control i/o pins, remote cameras...etc. it would not provide a stronger internet connection when communicating with a surface pro. It allows you to easily build iot controls that can serve a purpose. I fully intend on making many more iot videos in the future since it's a hot topic. Electronics is a hobby for me and I have found that wifi boards are a different animal.

@matthosini9656 2 роки тому

Good stuff, I enjoyed watching this. Not sure whereabouts I made mistake in my code. After I compile the code and open up the serial monitor, all I see is dot, which means it is not connected to WiFi. Could you please let me know your thoughts on this?

@BMonsterLaboratory 2 роки тому

Hi Matt. Sorry it took so long to respond. Did you try the code that I posted on the Facebook page? Do a Facebook search for #setupNodeMCU - If that doesn't work, let me know. I post most of the code for videos there because there's a larger character limit on comments. I'm sure it's probably just a simple adjustment. Merry Christmas! 👊👊

@BMonsterLaboratory 2 роки тому

Now that I Think about it...you may have to log into your router and open ports. I think I did this in the video. If you still need help, let me know. It is frustrating to get it up and running first time.

@matthosini9656 2 роки тому

Hello @@BMonsterLaboratory Merry Christmas! Thank you for your response. Yes, I've used your code on FB, and all I see are dots. No, I haven't logged into my router to open ports, and I'm not sure how I can do that. Could you please elaborate on this. I purchased the same ESP8266 that you are using in the video and it is brand new.

@BMonsterLaboratory 2 роки тому

I show the port forwarding in this video ukposts.info/have/v-deo/caRlgI2vqKSpt4U.html just skip to 5:35 and watch from there. This video is connecting a coffee pot to my wifi. I blot out my person ID numbers along the way but I think you can still follow it. My router is a TP-Link and there's a tutorial video on UKposts. You can probably find instructions for your brand of router on the manufactures web site. let me know what ya think.

@BMonsterLaboratory 2 роки тому

@@matthosini9656 So I finally got a chance to watch that video and go through all the steps and here is what I would check. 1. download the driver - you can see this at 2:25 2. in the video I have a pin at D4 even though this is GPIO2. this one is easy to miss. You can see the pinout at 4:53 3. make sure to include the ESP8266WiFi library in the code. 4. make sure your SSID is correcct. This is the name of your wifi. 5. make sure the password for your wifi matches the password in your code. You have probably done all or most of these. Hopefully you catch a small error in one of these points. I believe the dots keep appearing in the serial monitor because you are not connecting to your wifi. I would probably start with making sure the SSID and Password match. I certainly hope this helps because this stuff really is a lot of fun once you get it working.

Excellent video, very helpful. Now that my ESP8266 has a valid IP on my WiFi network, when I try to connect to that IP address I get a "The Site Can't Be Reached" message... (IP Address) refused to connect. Any idea what the issue could be?

@BMonsterLaboratory 10 місяців тому

Thanks! I assume you have the right SSID and password in the code. Did you press the reset button once you uploaded the program? Are there are any firewalls or port-blocking configurations on the network that might be preventing connections to the ESP8266?

@jeffreykatz5994 Рік тому

I am having problems making the connection from the Arduino IDE to the nodemcu 8266 12-E. In the dropdown, there is no com port choice to select from. I downloaded the ch340G driver twice, rebooted my pc, still no choice in the dropdown to select com port. I get message after compiling "Upload error: Failed Uploading: no upload port provided".

@BMonsterLaboratory Рік тому

hi Jeffrey! try switching USB ports and hopefully the option will drop down. which library are you using?

@BMonsterLaboratory Рік тому

I just plugged mine in and got the same thing. I'm using Arduino IDE 2.0 now so I have to download NTPClient from the library manager. I now get an option to select port. It works now. Make sure you select NodeMCU 1.0(EsP-12E) board as well. I hope that helps. Sorry for the long delay in replying.

Why specifically 220 ohm resistor please?

@BMonsterLaboratory 6 місяців тому

The ESP8266 operates at 3.3v which is too high for most leds. The led has a forward voltage of approximately 2v and operates at a current of 10-20ma. To calculate resistance to limit the current through the led, you can use ohms law, R=vsource-vLED/ILED or plainly, (R=V/I). You can use 130 or higher. I happen to have a ton of 220ohm resistor so, that's why I use that specific one... not sure if I have a 130 though. Anyway, great question. Thanks!

why is it need to reset?

@BMonsterLaboratory Рік тому

Hi Robert. The ESP8266 is pulled high by default. When you pull it low by pressing the button it will reset the board and allow you to see data on you serial monitor and connect to wifi. I've always had to reset after IDE upload with the 12E module to get the program started.

Hi . I have a prblem to connect this nodemcu esp8266 to arduino IED .. I paste the URL you told us . And when i opend the board manager and find the eso8266 community but it refused to download and gave me a message : Faild to install platform: esp8266. Error: 2 unknown: ) I will be thankful if you help me😊

@BMonsterLaboratory 11 місяців тому

Hey there! Are you stuck in the preferences section of Arduino IDE? Do other boards connect to Arduino IDE? Do you have a firewall or anything else preventing connection? Do you have all the same checked boxes in the preferences page as I do in the video? Your message just means there's an issue during installation of esp8266 platform. Is there any other error code? It's been a while since I had to do this, so I'll check it out on my own board.

@BMonsterLaboratory 2 роки тому

Hi Prajit! Where is your code? Feel free to email me at bmonsterlab@yahoo.com. Tell me what board you're using, copy/paste the code in the email, and tell me what you're trying to do (ex. LED blink, move a servo arm..etc.). I can see from what you've posted that you're trying to use a library that you don't have installed (#include "pins_arduino.h"). If you need to install a library called pins_arduino on you're IDE, that's an easy fix. Anyway, send me that email and will try to help as much as possible so you can be up and running. Thanks!
