Esp8266 Link For Arduino | Arduino On Esp8266

Introduction: Quick Start to Nodemcu (ESP8266) on Arduino IDE

Thanks to the guys those who ported the Esp8266 into Arduino IDE and helping all the arduino users happy to the core. Yes it’s been long time since they did and this post is bit later to thanks the good hearted work by the guys out there.

Lets begin with Installing the Esp8266 support for the Arduino and see how to blink an LED ( the hello world in the electronics )

check out the video to know step by step tutorial on how to get started with our favourite chip Esp8266

Firstly open the Arduino IDEGo to files and click on the preference in the Arduino IDE

copy the below code in the Additional boards Managerhttp://arduino.esp8266.com/stable/package_esp8266com_index.jsonclick OK to close the preference Tab.

After completing the above steps , go to Tools and board, and then select board Manager

Navigate to esp8266 by esp8266 community and install the software for Arduino.

Once all the above process been completed we are read to program our esp8266 with Arduino IDE.

For this example I have used NodeMCU esp8266 and if you are using any other vendor wifi chips or generic wifi module please check with the esp8266 Pin mapping which is very essential to make things works.

The reason why I used D7 pin for this example is , I uploaded the basic blink program that comes with the examples program in the arduino IDE which is connected with 13 pin of arduino. The 13th pin is mapped into D7 pin of NodeMCU.

go to board and select the type of esp8266 you are using. and select the correct COM port to run the program on your esp8266 device.

void setup() { // initialize digital pin 13 as an output. pinMode(13, OUTPUT); }

// the loop function runs over and over again forever void loop() { digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(13, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second }

upload the program and see the results.

if you like the above tutorial and if you want try out with cool projects you can also check this link here , that’s the amazon book link where you can use that book to make IoT with Esp8266 or Nodemcu, that books gives you basic coverage on how to do simple things and get yourself started with arduino and goes on developing projects like sending data to webserver and creating a webserver, uploading and controlling data from a webpage, how to interface TFT LCD and I2C devices and many more things can find on the link.

Step 2: Control Electrical Devices From User Web Browser Using Esp8266 Nodemcu

Make sure all the devices are connected to the same router, this example doesn’t include a port forwarding function which will not allow us to control the device from outside the home network.

Components that you need for completing this project are very simple, you need to have an esp8266 wifi module and a relay, make sure you buying a 5v relay which very easy to use with esp chips doesn’t require external supply too. we can make use of the Vin pin of the nodemcu or if you are using a generic chip, you need to supply an external 5v to the relay.

For this example project I have used only 2 relay circuit, but the actual program wrote for connecting four relay module.

You can check the above video on how this thing works and how to connect your browser to the ip address returned from esp and all the details are included in this video.

Copy the below arduino code and paste into your Arduino IDE and upload the program to your nodemcu or any other esp devices that you are using, make sure to choose the correct port and device name from the board. also don’t forget to change the SSID and password to your Wi-fi settings.

This program for the esp8266 wrote to return the status of the device , which will in turn notify us with the device state in the browser which will also make the user to know which device has currently turned on or off.

Copy the above code and complete the process. Share and let others know about this tiny chip which can do dozens of magic.

if you like the above tutorial and if you want try out with cool projects you can also check this link here , that’s the amazon book link where you can use that book to make IoT with Esp8266 or Nodemcu, that books gives you basic coverage on how to do simple things and get yourself started with arduino and goes on developing projects like sending data to webserver and creating a webserver, uploading and controlling data from a webpage, how to interface TFT LCD and I2C devices and many more things can find on the link.

Testing the Installation

To test the ESP8266 add-on installation, we’ll upload a simple code that blinks the on-board LED (GPIO 2).

Copy the following code to your Arduino IDE:


/********* Rui Santos Complete project details at https://RandomNerdTutorials.com/vs-code-platformio-ide-esp32-esp8266-arduino/ *********/ #include

#define LED 2 void setup() { // put your setup code here, to run once: Serial.begin(115200); pinMode(LED, OUTPUT); } void loop() { // put your main code here, to run repeatedly: digitalWrite(LED, HIGH); Serial.println("LED is on"); delay(1000); digitalWrite(LED, LOW); Serial.println("LED is off"); delay(1000); }



Uploading the Sketch

On the top drop-down menu, select the “unknown” board. A new window, as shown below, will open.

You should select your ESP8266 board model and the COM port. In our example, we’re using the NodeMCU 1.0 board. Click OK when you’re done.

Now, you just need to click on the Upload button.

After a few seconds, the upload should be complete.

The ESP8266 on-board LED should be blinking every second.

You can click on the Serial Monitor icon to open the Serial Monitor tab.

That’s it! You’ve installed the ESP8266 Boards successfully in Arduino IDE 2.0.

ESP8266 là gì?

ESP8266 là một module Wi-Fi với khả năng kết nối Internet và được tích hợp sẵn trên một số board nhúng như NodeMCU, Wemos, và ESP-01. ESP8266 có thể hoạt động như một điểm truy cập (access point), một client kết nối đến một điểm truy cập khác, hoặc cả hai đều được. Nó được sử dụng rộng rãi trong các ứng dụng IoT (Internet of Things) như cảm biến thông minh, hệ thống kiểm soát thiết bị, hoặc các ứng dụng điều khiển từ xa. Module này có giá thành rẻ và rất dễ sử dụng, cùng với đó là khả năng tương thích với nhiều loại vi điều khiển khác nhau.

Using git version¶

This is the suggested installation method for contributors and library developers.

Prerequisites¶

• Internet connection

• Arduino IDE 1.x or 2.x (https://www.arduino.cc/en/software)

• git (https://git-scm.com)

• Python ≥3.7 (https://python.org)

• terminal, console, or command prompt (depending on your OS)

• Uninstalling any core version installed via Board Manager

Instructions – Windows 10¶

• First, make sure you don’t already have an ESP8266 core version installed using the Board Manager (see above). If you do, uninstall it from the Board Manager before proceeding. It is also advisable to erase the Arduino15 contents.

• Install git for Windows (if not already; see https://git-scm.com/download/win)

• Open a command prompt (cmd) and go to Arduino default directory. This is typically the sketchbook directory (usually

  
C:\Users\{username}\Documents\Arduino

  where the environment variable
  
%USERPROFILE%

  usually contains
  
C:\Users\{username}

  )

• Clone this repository into hardware/esp8266com/esp8266 directory.

  cd %USERPROFILE%\Documents\Arduino\ if not exist hardware mkdir hardware cd hardware if not exist esp8266com mkdir esp8266com cd esp8266com git clone https://github.com/esp8266/Arduino.git esp8266

  You should end up with the following directory structure in

  
C:\Users\{your username}\Documents\


  Arduino | — libraries — hardware | — esp8266com | — esp8266 | — bootloaders — cores — doc — libraries — package — tests — tools — variants — platform.txt — programmers.txt — README.md — boards.txt — LICENSE

• Initialize submodules to fetch external libraries

  cd %USERPROFILE%\Documents\Arduino\hardware\esp8266com\esp8266 git submodule update –init

Not doing this step would cause build failure when attempting to include


SoftwareSerial.h

,

Ethernet.h

, etc. See our .gitmodules file for the full list.

• Download binary tools

  cd tools python3 get.py

• Restart Arduino

• If using the Arduino IDE for Visual Studio (https://www.visualmicro.com/), be sure to click Tools – Visual Micro – Rescan Toolchains and Libraries

• When later updating your local library, goto the esp8266 directory and do a git pull

  cd %USERPROFILE%\Documents\Arduino\hardware\esp8266com\esp8266 git status git pull

Note that you could, in theory install in

C:\Program Files (x86)\Arduino\hardware

however this has security implications, not to mention the directory often gets blown away when re-installing Arduino IDE. It does have the benefit (or drawback, depending on your perspective) – of being available to all users on your PC that use Arduino.

Instructions – Other OS¶

• First, make sure you don’t already have an ESP8266 core version installed using the Board Manager (see above). If you do, uninstall it from the Board Manager before proceeding. It is also advisable to erase the .arduino15 (Linux) or Arduino15 (MacOS) contents.

• Open the console and go to Arduino directory. This can be either your sketchbook directory (usually

  

/Arduino


  ), or the directory of Arduino application itself, the choice is up to you.

• Clone this repository into hardware/esp8266com/esp8266 directory. Alternatively, clone it elsewhere and create a symlink, if your OS supports them.

  cd hardware mkdir esp8266com cd esp8266com git clone https://github.com/esp8266/Arduino.git esp8266

  You should end up with the following directory structure:

  Arduino | — hardware | — esp8266com | — esp8266 | — bootloaders — cores — doc — libraries — package — tests — tools — variants — platform.txt — programmers.txt — README.md — boards.txt — LICENSE

• Initialize submodules to fetch external libraries

  cd esp8266 git submodule update –init

Not doing this step would cause build failure when attempting to include


SoftwareSerial.h

,

Ethernet.h

, etc. See our .gitmodules file for the full list.

• Download binary tools

  cd tools python3 get.py

If you get an error message stating that python3 is not found, you will need to install it (most modern UNIX-like OSes provide Python 3 as part of the default install). To install you will need to use


sudo yum install python3

,

sudo apt install python3

, or

brew install python3

as appropriate. On the Mac you may get an error message like:python3 get.py Platform: x86_64-apple-darwin Downloading python3-macosx-placeholder.tar.gz Traceback (most recent call last): File “/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/urllib/request.py”, line 1317, in do_open encode_chunked=req.has_header(‘Transfer-encoding’)) … File “/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/ssl.py”, line 1117, in do_handshake self._sslobj.do_handshake() ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)

This is because Homebrew on the Mac does not always install the required SSL certificates by default. Install them manually (adjust the Python 3.7 as needed) with:

cd “/Applications/Python 3.7/” && sudo “./Install Certificates.command”

• Restart Arduino

• When later updating your local library, goto the esp8266 directory and do a git pull

  cd hardware\esp8266com\esp8266 git status git pull

Maintaining¶

To keep up with the development branch

git switch –recurse-submodules –discard-changes master git pull –recurse-submodules cd tools python3 get.py

Pull requests¶

To test not yet merged Pull Request, first you have to find its ID number. This is the sequence of digits right after the pull request title.

Open terminal and cd into the directory where the repository was previously cloned. For example, 12345 is the Pull Request ID

git fetch origin pull/12345/head git switch –detach –recurse-submodules –discard-changes FETCH_HEAD

When Pull Request updates packaged tools, make sure to also fetch their latest versions.

cd tools python3 get.py

To go back to using the development branch

git switch –recurse-submodules –discard-changes master git pull –recurse-submodules

Step 4: Selecting the Board and Port

After installing the ESP8266 Arduino Core, restart your Arduino IDE and navigate to Tools > Board to ensure you have ESP8266 boards available.

Now select your board in the Tools > Board menu (in our case, it’s the NodeMCU 1.0 (ESP-12E Module)). If you are unsure which board you have, select the Generic ESP8266 Module.

Finally, connect the ESP8266 NodeMCU to your computer and select the Port.

That’s it! You can now begin writing code for your ESP8266 in the Arduino IDE.

You should make sure you always have the most recent version of the ESP8266 Arduino core installed.

Simply navigate to Tools > Board > Boards Manager, search for ESP8266, and verify the version you have installed. If a newer version is available, you should install it.

Testing the Installation

To test the ESP8266 add-on installation, let’s see if we can blink an LED with the ESP8266 using the Arduino programming language.

Parts Required

Here’s the hardware that you need to complete this project:

If you’re using an ESP8266-01, you also need an FTDI programmer to upload code.
