# RotaryHueControl

Control colors on a Common Anode RGB LED diode using a 5 pin 360° rotary encoder and a basic rotary potentiometer, or built-in web interface commands.    

    



  

  

  

  



## Network Info:

This program requires internet to function - make sure to change the ssid and password variables in main.cpp to match your network settings. You may also need to change the subnet, gateway, and local_ip variables.    



## Functionality:

* 360° Rotary encoder color controls - spinning the rotary encoder will cycle the LED diodes through the color spectrum.

    * Rotary encoder power controls - pressing the rotary encoder's built-in button will toggle the power state of the LED diodes.

* Potentiometer brightness controls - spinning the potentiometer will modify the brightness level of the LED diodes.

* Internet Serial Interface - includes WebSerial library to allow serial monitoring and input over Wi-Fi (http:///webserial)

* Internet based controls via WebSerial input:

    * /color r g b - Allows you to set the LED color to a specific RGB value.

    * /state - Reports whether or not the light is on.

    * /restart - restarts the ESP device.

* Internet connection status indicator: Red onboard LED will turn on anytime the ESP is not connected to a Wi-Fi network.

* OTA Updates - includes ElegantOTA library to allow for Over-The-Air firmware updates (http:///update).    



# Specifications and Pinout

All builds were created and tested using the PlatformIO IDE extension for VSCode and Espressif ESP8266 NodeMCU board paired with a rotary encoder from an old alarm clock. Mileage may vary using other boards, IDE's, and rotary encoders.    

    

The following libraries are required (for basic and network functions):

* [Elegant OTA](https://github.com/ayushsharma82/ElegantOTA)

* [WebSerialDark](https://github.com/mwdle/WebSerialDark)

* [EncoderStepCounter](https://github.com/M-Reimer/EncoderStepCounter)

* [ESPAsyncWebServer](https://github.com/me-no-dev/ESPAsyncWebServer)    



## Pinout Info:

* encoderPin1 is the 'a' pin on your rotary encoder. This program uses pin D2 on the ESP8266 NodeMCU.

* encoderPin2 is the 'b' pin on your rotary encoder. This program uses pin D1 on the ESP8266 NodeMCU.

* button is the button pin on your rotary encoder. This program uses D3 on the ESP8266 NodeMCU.

* pot is the output pin on your potentiometer. This program uses A0 (ADC Pin) on the ESP8266 NodeMCU.

* redPin is the red pin on your _Common Anode_ RGB LED diode. This program uses pin D5 on the ESP8266 NodeMCU.

* greenPin is the red pin on your _Common Anode_ RGB LED diode. This program uses pin D6 on the ESP8266 NodeMCU.

* bluePin is the red pin on your _Common Anode_ RGB LED diode. This program uses pin D7 on the ESP8266 NodeMCU.

* errorLED is the pin of your onboard red LED. This program uses pin 16 on the ESP8266 NodeMCU.
