Wemos Websocket LED

The Arduino's Wemos Websocket project, by Clever Cloud.

The Wemos is connected to a LED strip. This strip is a gradient defined by two colors. When a new color is selected, the gradient goes from the new color to the old one.

Interact with the strip

You can change the color of the strip thanks to the interface given by the wemos-ws-led-backend project.

The websocket client waits for a string that defines the color (format: RRRGGGBBB).

🚨 If the first LED flashes red, the connection is closed. Verify your network configuration and restart the Wemos.

Installation

Hardware

Connect the LED strip to the Wemos using the small cables:

  • Connect the red cable of the LED strip to the +5V of the Wemos
  • Connect the white cable of the LED strip to the GND (ground) of the Wemos
  • Connect the green cable of the LED strip to the D4 of the Wemos

Here is how it should look like: howitshouldlooklike.jpg

Now, plug the Wemos into your computer.

Software

On Linux, it should work out of the box.

For Windows and Mac OS, you need to dowload a driver: https://wiki.wemos.cc/downloads

For Mac OS, here is a detailed article on how to get started with Wemos: https://blog.rjdlee.com/getting-started-with-wemos-d1-on-mac-osx/

Arduino IDE

Install the Arduino IDE: https://www.arduino.cc/en/Main/Software

In order to interact with the Wemos, you have to configure the Arduino IDE. If you can't find the WeMos D1 R2 & mini board in Tools > Board, do the following:

  1. Open preferences File > Preferences.
  2. Add the line "http://arduino.esp8266.com/stable/package_esp8266com_index.json" in the Additional Boards Manager URLs field and close Preferences.
  3. Open Tools > Board > Boards Manager and search ESP8266.
  4. Install the ESP8266 by ESP8266 community.
  5. Choose the WeMos D1 R2 & mini in Tools > Board.

You also have to clone the two git repositories specified at the top of the file https://github.com/CleverCloud/wemos-ws-led/blob/master/clevercloud-wemos-ws-led.ino into the libraries folder. (open File > Preferences and look at the Sketchbook location to find the libraries path).

You should also clone this repository under the path where your Arduino IDE is installed

Upload to the board

  1. Select the right USB port in Tools > Port.
  2. Change the SSID, wifi password and the hostname (your_app_id.cleverapps.io).
  3. Click on the Verify button.
  4. If there is no error, Upload it to the Wemos.
