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?
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! 👊👊
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.
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.
I show the port forwarding in this video th-cam.com/video/9t4LWxqnxVQ/w-d-xo.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 TH-cam. You can probably find instructions for your brand of router on the manufactures web site. let me know what ya think.
@@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?
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?
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?
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.
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".
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.

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😊
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.
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!
If you just want to find the IP address for your ESP8266, try this: #include const char* ssid = "YOUR_SSID"; const char* password = "YOUR_PASSWORD"; void setup() { Serial.begin(115200); delay(10); // Connecting to Wi-Fi network Serial.println(); Serial.print("Connecting to "); Serial.println(ssid); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(""); Serial.println("WiFi connected."); Serial.println("IP address: "); Serial.println(WiFi.localIP()); } void loop() { // Put your main code here, to run repeatedly: } 👍
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.
