Pin 2 has an integrated LED - configure it, and turn it off In my case my home network runs with SSID SCOTLAND, and password Highlander1 - if you're nearby feel free to connect! #include The sample code needs to be updated to include your WiFi details. Run a HTTP server which will allow an LED to be controlled.We'll take advantage of that in this first sample program, by writing a program which will: The single biggest difference between the D1 board and the other Arduino devices I've used so far is that it has on-board WiFi. " menu-item to select the "WeMos D1 R2 & Mini" board we're using. To complete the setup we'll now use the " Tools | Board. In the resulting dialog you can now enter "ESP8266" in the filter-section, and that will then let you install the appropriate supporting libraries, headers, and board-descriptions. " menu-item, and choose " Board Manager" from the top of the list. Once you've done that you can open the board-manager via the " Tools | Board. In the section "Additional Board Manager URLS:" enter the following URL: Open the preferences display via the " File | Preferences" menu-item. Now the 1.8.0 studio doesn't contain support for the WeMos D1 Mini - so we need to add it. To run the IDE you'll need to install the openjdk-8-jre package, via the backports repository. The current stable release of Debian GNU/Linux includes openjdk-7-jre, which is sadly too old to run the project. The project is written in Java, so you'll need to have a suitable runtime installed. To write your code, and upload it to your board over the USB cable, you'll need to install the Arduino IDE, which is currently version 1.8.0. NOTE: My user is a member of the plugdev group, so I can now read/write to the device. We'll do this by creating a local udev rule in the file /etc/udev/rules.d/les - create that file, and give it the following contents: So I know the USB-device which appeared is the WeMos D1 device, which was described by this line: Bus 001 Device 005: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapterīy default the permissions are configured such that I cannot read/write to the device, so we'll fix that, and create a handy symlink for ease of future identification.

Run lsusb, then plug in the board, and finally run it again. The simplest way to find out what the new device is called is to use the lsusb utility which will show you your connected USB devices. The new device will be called /dev/ttyUSB0, or similar. Once connected to your system you should find you have a new device appear, thanks to the wonders of hotplugging. I've bought seven, just so I don't run out! Identification & Permission Setup The board features:īuying from AliExpress, or similar, these can be had from as little as €3, even in single quantities. The WeMos D1 Mini is a board which is built around the ESP8266 chip.
