We will be taking things slow and covering all the basics. By the end of this guide, you will understand how the WeMos D1 Mini works and how to use it in your projects. So, let’s get started!

What is a WeMos D1 Mini Tutorials?

A WeMos D1 Mini is a small Wi-Fi-enabled board based on the ESP8266 chip. It has 18 digital input/output pins (of which 4 can be used as PWM outputs), a micro USB port, a power jack, an ICSP header and a reset button. The WeMos D1 Mini is a great way to get started with ESP8266 development.

The WeMos D1 Mini is perfect for prototyping and for building IoT applications. The board is very similar to the popular NodeMCU board but with a smaller form factor. The WeMos D1 Mini is available in two variants: the D1 Mini and the D1 Mini Pro. The Pro version includes an onboard USB-to-serial converter and a LiPo battery charging circuit.

WeMos D1 Mini Pinout Tutorials

When it comes to electronics, the WeMos D1 Mini is a true powerhouse. This tiny little board has a massive amount of pinouts and capabilities, making it the perfect choice for a wide range of projects. WeMos D1 mini has a whopping 16 GPIO pins. This means that you can easily connect a wide range of devices and components to the board, giving you the ability to create some truly amazing projects.

How to get started with the ESP8266 WeMos D1?

In order to get started, you will need the following: -WeMos D1 -Arduino IDE (or other compatible IDE) -USB cable The next step is to connect the WeMos D1 to your computer via the USB cable. Once it is connected, you can then open the Arduino IDE and select the correct board type and port. With the board and port selected, you can then load up any sketches or programs you want to run on the WeMos D1.

Wemos D1 ESP8266 Getting Started Guide With Arduino IDE

  • First, you’ll need to download the Arduino IDE. You can get it for free from the Arduino website.
  • This role is pretty self-explanatory and I won’t go into how to install a program.
  • Guide to the https://www.arduino.cc/ and download the right IDE for your operating system.

Download and Installing the CH340G Drivers (Windows)

I have been using the esp8266 CH340G drivers for a while now and they work great. I have never had any problems with them and they are very easy to install. I would recommend them to anyone who is looking for a good way to connect their esp8266 to their computer.

The CH340G is a cheap serial to USB programming chip and does not come with native windows or mac drivers. However, it has been made very easy to install. Download and install the drivers from this website:

Installing the Libraries

Once you have the IDE installed, open it up and go to the File > Preferences menu. In the “Additional Boards Manager URLs” field, add the following URL:

httparduino.esp8266.comstablepackage_esp8266com_index.json

http://arduino.esp8266.com/stable/package_esp8266com_index.json

httparduino.esp8266.comstablepackage_esp8266com_index.json

This will add support for the WeMos D1 Mini to the Arduino IDE.

  • Select from the Tools menu Board: * > Boards Manager…
  • Type in esp8266
  • You should see a listing for esp8266 by ESP8266 Community
  • Click Install
  • Click Close

install arduino ide to esp8266

Next, go to the Tools > Board menu and select “WeMos D1 mini“. Now you’re ready to start writing code for your WeMos D1 mini. Just create a new sketch (File > New Sketch), and start coding away.

  • Select Tools > Board: *
  • Select board (LOLIN(WEMOS) D1 R2 & Mini)

Uploading the example Blink sketch on Wemos d1

  • Go-To Select File > Examples > 01. Basics > Blink
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}
