WiFiLed

With this project, you can control an WS2812 RGB LED stripe (up to 300 LEDs) via your browser.
The following features are realized.

• browser control
  The device provides a webpage, where you can control the LED stripe (including simple animations).
  
• smooth on/off
  The LEDs will be turned on and off smoothly via a PT1 damping
• rightness is dependent form sunrise & sunset
  You can define two different brightnesses, one for sunrise and one for sunset.
  The brightness switches automatically when the sun rises or sets.
  
• color animations
  You can define simple color animations
  
• sunrise & sunset calculation
  You can configure NTP timing servers and your longitude and latitude, to calculate the sunrise and sunset.
  
• optionally IR motion sensors
  Connect optionally two IR motion sensors to activate the LEDs by motion detection.
  After a defined time the LEDs will be durned off.
  
• optionally IR distance sensors
  Connect optionally an IR distance sensor to control on/oof and the brightness.
  
  • fast moving across the distance sensor turns the LEDs on/off
  • static distance in front of the distance sensor changes the brightness

Compile & Flash

1. open project root in your VSCode editor
2. connect device Wemos D1 mini via USB
3. configured the connected COM port in ./platformio.ini
4. open your PlatformIo VSCode plugin
5. select in PlatformIo / d1_mini / Platform / Upload Filesystem Image to upload the Sketch data stored in ./data/
6. select in PlatformIo / d1_mini / General / Build to build the system
7. select in PlatformIo / d1_mini / General / Upload and Monitor to upload the code and start the serial monito to see the debug output

Debug output

This project sends a lot of debug information via the serial interface. These data will be sent with 115200 baud.
You can control which information should be sent, when you change the DEBUG_LEVELin file DebugLevel.h

WiFiLed/DebugLevel.h

Getting Started

When you turn on as first time, follow the next steps, to connect the device in your WiFi:

1. The blue onboard LED is blinking slowly to inform you, a Wifi-Access-Point was started.

2. Search and connect your mobile device with an WiFi-Access-Point named WiFiLed-\<DeviceId\>
   

   name	value
   SSID	WiFiLed-<DeviceId>
   Password	none
   Url	http://192.168.4.1/

3. Open in your browser the page http://192.168.4.1/

4. In WiFi Setup add your WiFi SSID and password and press Success
   

5. The device starts new, but with a fast blinking onboard LED to inform you, the connection to your WiFi is trying

6. When the WiFi connection is successfully established, the onboard LED is static on.
   

   • Search in your router the IP from device
   • open the IP in your browser to control the LED stripe

7. When the WiFi connection fails after 3 minutes, the device will restart, but im WiFi-Access-Point mode (slow blinking onboard LED)
   Repeat all steps from begin
