Arduino Tutorial: First look at the WeMos D1 Arduino compatible ESP8266 Wifi Board from Banggood.com

8 років тому

In this video we take a look at the WeMos D1: a Wi-Fi enabled Arduino compatible board based on the ESP8266 chip. The price of it is so tempting, less than 9$. Without any second thoughts I ordered it a few days ago I received it and started working with it.
The board looks like an ordinary Arduino board. The dimensions and the pin layouts are exactly the same. So, this board is compatible with all the existing shields for Arduino. But don't expect them to work at once, since the libraries available for the ESP8266 chip are few so far. The board, instead of an ATMEGA chip that standard Arduino boards use, use the impressive ESP8266 WiFi chip!
The ESP8266EX chip that the WeMos D1 board uses offers:
• A 32 bit RISC CPU running at 80MHz
• 64Kb of instruction RAM and 96Kb of data RAM
• 4MB flash memory! Yes that's correct, 4MB!
• Wi-Fi
• 16 GPIO pins
• I2C,SPI
• I2S
• 1 ADC

Thank you so much for this wonderful tutorial, I was about to teardown my D1 board thinking it won't work until I saw this.

@johnturcott9998 7 років тому

I've had a WeMos D1 R2 for about 2 months and all but given up on Arduino IDE ESP8266 SPI projects that I've found online. Your example, after switching pins from SDA and SCL to D3 and D5 worked perfectly. Thank you!

@JerryEricsson 7 років тому

Wow thanks a million! For some reason I kept looking for the flash button on this device, at last some time last night while digging around on the Internet, I found the information that some of these boards do not need the flash button, or a jumper set to flash. So I followed your lead and uploaded the blink program and it works!! Now I can use this board for something when the need arises. Perhaps a wireless thermometer or something that displays on my cell phone, mounted under the hood of our RV so it is out of the sunlight but still protected from the engine heat by the insulation that is built into the system!

@fredflintstone8048 8 років тому

As usual your work is greatly appreciated. Thank you for sharing. I'm going to get one of these and start working with it.

There are so many "channels" that purport to explain things or teach you something. Most of them work really hard to cram 5 minutes of information into a 25 minute video (often because they don't edit before posting). Your site is a wonderful exception. You cram 10 minutes of information into a 5 minute video -- I can always stop and go back but I will never die of boredom. Thanks. This video was just what I was looking for!

@Educ8s 8 років тому

+FranzStrasse Thank you very much for your comment. I am glad that my aproach to video creating is well received. I think that viewer's time is valuable and I don't want to waste not a single second of it. I am going to publish a new video about the impressive Wemos D1 soon. Stay tuned!

@markcast6841 7 років тому

Great video. I thought this was an add on to the UNO. So can this board be used as a stand alone system? I would like to make something that will text/email me if a sensor is triggered, like an alert board if my sump pump fails.

@Jevist 7 років тому

Help needed! Thanks for this example, I used the code example and it worked pretty well (I removed all OLED references as I just wanted to try out the WIFI functionality). In 99% of the cases the example code is correctly showing a result of 14 characters: It works fine! Every now and then however, the result is: It works fine!ÿ Note the additional ÿ at the end! Still, the length is reported to be 14 characters, so it seems to recognise that only 14 bytes were received, yet somehow reading the ethernet buffer spits out this extra character under some circumstances? Would love to understand this, to make sure I can apply it in a robust failsafe solution.

@rafaelmarroquin4429 8 років тому

Great video, I bought one of them but on Ebay, but still not coming :D

And what needs to be changed or added to the sketch in order to register two access points (that is, two WiFi networks)? If one doesn't work, will it connect to the other by itself?

With the Wemos D1, i mentionned that it was quite slow. In fact the client.println() is very slow. So to make it faster, it is better to concatenate all the strings together and then to send the command client.println(TotalString);

@Gabriel-iu5ow 8 років тому

Could you give me the link of the libraries?

@squalazzo 8 років тому

hi, can normal shields be mounted on top of this board without problems? I think to different logic levels, in general esp8266 is 3.3v while arduino is 5v... or wemos implemented some kind of logic level translations to make the D1 5v tolerant?

@arjanvandewiel574 8 років тому

Strange, can you make a video about the pins?

@squalazzo 8 років тому

+Arjan van de Wiel what video? the pins of the esp8266 are in the link in video description, which states that all IO is at 3.3V, while standard arduino is 5v, and most sensors work at 5v, too...

@arjanvandewiel574 8 років тому

+squalazzo All the standard shield work on 5V logic, which can damage the board. Are there logic shifters on board?

@squalazzo 8 років тому

+Arjan van de Wiel no shield has logic shifters... so, what's the point to have standard arduino pinout on this board if you cannot use the shields, anyway?

@edgeeffect 8 років тому

That's a lot of I2C ports!

@IstvanNagy86 8 років тому

It's not an Arduino. It's an ESP8266 in the form factor of the Arduino Uno. Yes, you can compile stuff for the board with the Arduino IDE, but you don't have to. You have NodeMCU, Espruino, bare metal C/C++ on your hands. Even Basic is available if that's your heart's desire. You can use Sming or Platform.io. And yes, this doesn't have as many libs as the Arduino, still the number of libs available is steadily growing. And performance wise this easily beats any Arduino. I think the biggest weakness is the lack of hardware timers and PWMs of the ATmega. Maybe the ESP32 chip will solves this, it's on the hoirzon and available soon.

@venkateshe7506 8 років тому

+István Nagy platformio is not framework but a platform. Sming is a framework and yes it needs to evolve, but it works just fine.

hi one question i wanna know th names of the analog pins, if the first one is A0 the second one is A1? coz i cant connect in the analog pings thxs

That's one of the biggest disadvantages of the ESP8266 chip. It has only one Analog Pin, A0.

Will this board work with BLYNK?????????????????????????????????

@adlapl 7 років тому

You say that: "The board looks like an ordinary Arduino board. The dimensions and the pin layouts are exactly the same. So, this board is compatible with all the existing shields for Arduino." // Well, with TFT-shield as well? Yet, WeMos has no all (UNO R3 standard) analog pins available - only one. Good question is - why?

@Educ8s 7 років тому

Hello Adam, The reason for this is that the ESP8266 chip only has 1 analog input. The new ESP32 chip has many more analog inputs so we can expect fully compatible boards with the existing shields in the near future.

Arduino better step up their game... they just got left in the dust. I think it has some stability issues and I had trouble with PWM, but hopefully some later ESP8266 firmware updates will resolve them.

@googissoftware 6 років тому

OK, first of all this is the link in the video to add in preferences->additional boards: arduino.esp8266.com/stable/package_esp8266com_index.json Now, i kept getting "espcomm_open failed" message - this is how i solved it: MY upload speed didn't have an option like in the video for 155200, so i used 115200 in the arduino IDE (tools upload speed). Then i set the com port device port speed to be the same: right click "computer"->properties->device manager, open the ports (COM & LPT) right click the com port you are using and choose properties, "port settings" tab and change bits per second to 115200. then ok. After this the example program worked fine with a blinking led.
