This time I decided to try the Arduino Web Editor as I could save all of my scripts to my account and not need to worry about preserving them if I ever re-installed my OS again or upgraded to a new machine, which is long overdue.

The ESP8266 community created an add-on for the Arduino IDE that allows you to program the ESP8266 using the Arduino IDE and its programming language. This tutorial shows how to install the ESP8266 board in Arduino IDE whether you’re using Windows, Mac OS X or Linux. Before starting this installation procedure, make sure you have. We will learn how to install the ESP32 board in Arduino IDE 2.0 whether you’re using Windows, Mac OS X or Linux. More ESP8266 projects you can find here.

It took me way too long to get started with the WeMos D1 R2 board, partly because mine is an eBay knockoff.

1. Download and install the Arduino IDE (just called Arduino): https://www.arduino.cc/en/Main/Software Note: I use version 1.6.8, newer versions may not work.
2. Open Arduino
3. Open File → Preferences
4. Copy and paste http://arduino.esp8266.com/stable/packageesp8266comindex.json into Additional Boards Manager URLs field. You can add multiple URLs, separating them with commas
5. Open Tools → Board:xxx → Boards Manager and install esp8266 by ESP8266 Community

1. Open Tools → Board:xxx and select WeMos D1 R2 & mini.
2. Open Tools → Upload Speed and select 115200. If you're brave, you can try 230400 to upload code to the board faster, but watch the console for errors.
3. Download a driver so your Mac recognizes the WeMos D1 board (the site looks sketchy, but I can confirm the driver is legit): Note: This driver is needed for both real and knockoff D1 boards. http://www.wch.cn/download/CH341SERMACZIP.html

1. Plug your WeMos D1 board into your Mac using a micro USB.
2. Open Tools → Port:xxx and in the dropdown, select the option with 'usb' in its name.
3. Your Tools dropdown should look like this:

1. To make sure everything is working properly, let's download WeMos' example files: https://github.com/wemos/D1miniExamples/archive/master.zip
2. Rename the uncompressed directory to D1miniExamples
3. In Arduino, open File → Preferences
4. In Finder, navigate to the Sketchbook location show in in Arduino's Preferences
5. Move the D1miniExamples directory to Sketchbook location
6. The path will look like Sketchbookdirectory/D1mini_Examples
7. Restart the Arduino IDE
8. All examples are under File→Sketchbook→D1miniExamples

1. Open File→Sketchbook→D1miniExamples→01.Basics→HelloWorld
2. Click Upload
3. After upload, open Tools→Serial Monitor, set baudrate to 9600 baud

If you've gotten to this point, good work! Now we're going to learn a bit more about the WeMos D1's I/O ports. They're f***ed.

The fact that I have a knockoff board doesn't help either. Anyways, enough complaining. Basically, the labels on the WeMos D1 are not the same as those used in Arduino programs.

As an example, if I want to use digital port 3 (D3) as an output, this is the code I would use:

I've created a couple of reference tables for your convenience.

Note: I can't guarantee the official WeMos D1 board mappings are correct, but they're based off this:
http://www.instructables.com/id/Programming-the-WeMos-Using-Arduino-SoftwareIDE/?ALLSTEPS

1. Restart the Arduino IDE
2. Try a different micro USB cable
3. In Finder, navigate to ~/Library (to get to Library, click on Go, then press control, and click on Library). Rename Arduino15 to Arduino15-backup.Download and install the latest version of the Arduino IDE (replace your current version)Open Arduino, re-install esp8266 in the Boards Manager.

If you have any other troubleshooting tips, send them my way.

A good amount of the content here is based on the official WeMos documentation ( http://www.wemos.cc/tutorial/getstartedin_arduino.html ). I've simply filled in many of the gaps preventing my board from functioning properly.

This is what an actual WeMos D1 board looks like:

This is what my knockoff WeMos D1 board looks like:

Now you know how to set up your WeMos D1 board and use its ports. I'm going to leave out discussion on its WIFI capabilities because there's plenty of documentation on that already.

In the next article, I will discuss how to connect a stepper motor to the WeMos D1.

Hi,

i just try to put some software onto an Arduino Mega. I've connected USB and also tested with external power but it seems the USB->Serial connection isn't established. I can't see the serial port in the list - only the bluetooth related stuff from the system.

I'm using Arduino 1.0 (downloaded yesterday) - any idea what may go wrong? Tried rebooting but didn't help. Couldn't find anything helpful through google so far.

Thanks,Frank

EDIT: Tried under Windows and works - so the board seems to be ok just there's no serial port on the Lion.
