First time using Wemos D1 mini I did the led blink then the WiFi test both worked first time so now I know my D1 works fine thank you, so onwards and upwards cheers for your help "Bob in the UK"
I am confused by how we refer to PIN numbers on the esp boards. If I put a sensor wire into pin D8 on the Wemos can I just say in setup: pinMode(D8, INPUT); and later in my code: attachInterrupt(D8, Flow, RISING); ? Do I need to include some kind of a legend to say D8 is some other number? Are the numbers different for interrupts? Thank you.
@@robojax Thank you for the reply. But I don't follow. Can you point me to where you have discussed interrupts on the Wemos? I am struggling to connect a water flow meter (using Hall effect) to my Wemos. I got the project working on my Nano. But the same code is not working with the Wemos. I have looked on your tutorial page but saw no similar projects. Please help. Thanks.
The reason I asked about pin numbers is in your project "APDS-9960 Gesture sensor with Arduino" you initialized the sensor pin at 2 but when you called the interrupt you had to call it 0. If you did the same project using a Wemos board how would you refer to the pin? Thank you.
its actually 4MB of external flash for things like program storage. Its something like 128kb of sram, including whatever gets used by the firmware for running the wifi stuff.
Great video! thank you so much! I am learning this to program an RGB light display, a Christmas present for my girlfriend :) This is my first time programming in arduino, and your tutorial is so helpful!
when I want to erase it on Windows and Python installed, with command ESPTOOL.PY -P COM2 ERASE_FLASH it gives me error: no data received Do I have to put it in DOWNLOAD MODE or something like that? Thanks for answer me
3 projects in one. 1-measure voltage over 5V 2-Connected send over WiFi 3-Database application and saving. I've shown the Analog pins. you mean learn from my other Arduino videos. just search my channel
I'll try one more time. I recently purchased a robojax Wemos D1 Mini board off Amazon. I am trying to use it with a Hall effect water flow sensor. I know the sensor works because it functions fine with my nano. I just cant get it working with Wemos. Can you point me to a project on the web that can walk me through the code of getting the Wemos board to work with this sensor? The sensor basically sensor a pulse every time the water wheel spins.The code needs to keep track of the pulses, which can come very fast. On the nano I set up a simple project using an interrupt. The same code won't work on the Wemos. Please help.
Hello, I am not sure what kind of sensor you and what type of code you use, it should work with esp8266, if it has I2C, then check my videos to know the I2C pins. Generally it should work.
Downloaded and installed driver to NodeMCU Lua ESP8266 ESP-12 WeMos D1 Mini. Selected ESP8266 Blink sketch as per video which compiles but does not download. Massive error message that ends in "or esptool directories not found next to this upload.py tool. An error occurred while uploading the sketch". No idea how to fix this!
I just checked. this is very simple code. you have no provided any error. Read the error. only one line will tell you why. or take screen shot and post it here snipboard.io/ and then share the link back here
sorry I didn't get it. USB is Input and not output. So you can connect it to a wall charger or computer to power this module. We have 5V and 3.3V pin on the module you can use.
Robojax thank you for fast replay, i am totally lost and i want to make the connection and setup , programing. Someone on telegram said i need to buy wemosd1 , other one said i need uart usb. But when i went to the shop he is you dont need because it already has arduino on it , can you help me?
hi, I am new to Arduino. I had followed the video, but the Arduino IDE cannot detect my D1 mini (COM1 or COM3). Do you know why? I had tried 2 boards, they were all the same.
you need to install the driver for it then. Perhaps this is the driver. ua-cam.com/video/u_21yNqd03I/v-deo.html this could be the same chip follow this video.
did you did not find what? There is is the Driver for ESP8266. The link is under the video. you need to prepare the board as I've shown. then it is ready. for the code example, I just checked it the link works and there is nothing missing. once you click on the link, the page is full of information and links.
Thank you for the video, very instructive. One problem that I encounter is the very bad wifi-connection of this board in your video( and mine). It is totally unpredictable if the board connect yes or no, and if it has connection, it looses connection(90% of the time it is searching for connection). My other board(arduino-uno-esp8266-board is working fine with the same sketch in the same router environment. Do you have suggestions?
You are welcome. I have no issue with WiFi as I am very close to Wifi router. If you have a serious practical application, then get a module that has external Antenna and it should resolve the issue.
Sir your "Wemos D1 Mini NodeMCU WiFi ESP8266" card is not connected normal arduino isn't it ? You are only feeding the chip with usb voltage ? And you are installing all libraries on the Wifi module ?
hi, I encountered such a problem, I have 20 wemos d1 mini v3.0.0 boards, but none of them find my networks in client mode, and no device (laptop, smartphone) sees wemos in AP mode. but they see each other (1 wemos create point - 1 wemos scan). Tell me how to deal with such a problem. Has anyone come across?
One thing that i faced was the SSID is case sensitive. "Book" is not the same as "book" with this device. But on the phone or tablet, any upper or lower case works.

Thanks for the video. Just have one question. Can we use pin 5V pin as vcc meaning the power input to operate the device?
Hi, yes you can input 5V. That pin is directly connected to USB where it gets 5V from USB.
when I want to erase it on Windows and Python installed, with command ESPTOOL.PY -P COM2 ERASE_FLASH it gives me error: no data received
Do I have to put it in DOWNLOAD MODE or something like that? Thanks for answer me
Can I control 1 sensor and results control 5v water pump on /off as needed by sensor?with this?
yes you can. I have tones of videos for Arduino. Most sensors works with this . yes.
I have a forklift that has a 60V battery. I would like to measure and write the voltage into a database via WiFi. How can I measure the voltage?
3 projects in one. 1-measure voltage over 5V 2-Connected send over WiFi 3-Database application and saving. I've shown the Analog pins. you mean learn from my other Arduino videos. just search my channel

Great video, thanks for the share. Can the Arduno also run on sim module, to work where there isn't wifi?
Wifi feature is needed if you want to connect to something wirelessly. If you don’t need it, all other features work like a normal microcontroller
Hello, can you tell me. Which one, wemos d1 mini or nodemcu esp8266 and state your reason
All of them are ESP8266. Because of the shape they have different names. Please watch this video ua-cam.com/video/pLvqh57T3s4/v-deo.html
@@robojax oh okay. But i want to know your answer, hehe
Downloaded and installed driver to NodeMCU Lua ESP8266 ESP-12 WeMos D1 Mini. Selected ESP8266 Blink sketch as per video which compiles but does not download. Massive error message that ends in "or esptool directories not found next to this upload.py tool.

No idea how to fix this!
So not copy and paste. Click in the download button. Usually browsers are making them useless.
@@robojax Many thanks for the quick response. Please clarify exactly what you say I should download and what to do after download...

What's that relay you have? I need one of those to control my appliances!
it is called relay. Simple and I have mentioned it.
love it keep it up
Thank you. Please subscribe. I appreciate it and helps my channel grow. Thank you
i have a question, can we use 3v instead of 5v of the usb port?
sorry I didn't get it. USB is Input and not output. So you can connect it to a wall charger or computer to power this module. We have 5V and 3.3V pin on the module you can use.
Correct me if I'm wrong but isn't the ADC of ESP8266 only rated for voltages of 1 volts and lower?
A0 is rated at 3.2V see it in this page: wiki.wemos.cc/products:d1:d1_mini
Hello
how can i know my model i have ?
infront it said esp-12F , and on while color : D1 mini
below on chip : ch340c , then 205665930
is it esp 8266 ?
Hello, very simple. If you can upload blink code the way I’ve show , then it is esp8266

hi sir! how to connect wemos d1 mini with l293d motor drive?
Hello, that needs separate video. I have it in my list. Will make video when time permits.
When I plug this in my PC powers it but I don't see it show up on my PC under Device Manger. It's like it doesn't exist what am I doing wrong?
I will reply to all subscriber's 🔔 questions. So make sure to subscribe.😊

I also encountered this, but here the problem lies in different frequencies, or something else. and where I can’t configure it.
ESP8266 is working on 2.4gHz and if your router is 5.8gHz this device will not see it.
Robojax all my devices work on 2.4ghz in b / g / n, but he still cannot find them ...
Nice one sir
Thank you.
Thanks a lot
