Piyush Shah f4767018f9 ws2812_led: Simplify WS2812 RGB LED handling logic and also allow disabling it

The common code for WS2812 RGB LED has been moved to a component ws2812_led.

The WS2812 LED is available only on ESP32-S2-Saola-1 boards and hence
it will be enabled only if IDF target is set to ESP32S2. It can
be disabled by disabling the CONFIG_WS2812_LED_ENABLE config option.

led_strip component files have also been moved to ws2812_led

Temperature Sensor Example

Build and Flash firmware

Follow the ESP RainMaker Documentation Get Started section to build and flash this firmware. Just note the path of this example.

What to expect in this example?

This example uses esp timer and the RGB LED on the ESP32-S2-Saola-1 board to demonstrate a temperature sensor.
The temperature value is changed by 0.5 every minute.
It starts at some default value (25.0) and goes on increasing till 99.5. Then it starts reducing till it comes to 0.5. The cycle keeps repeating.
The LED color indicates the temperature.
LED hue changes from 200 (bluish) to 0 (reddish) as the temperature increases from 0.5 to 99.5.
You can check the temperature changes in the phone app.

LED not working?

The ESP32-S2-Saola-1 board has the RGB LED connected to GPIO 18. However, a few earlier boards may have it on GPIO 17. Please use CONFIG_WS2812_LED_GPIO to set the appropriate value.

Reset to Factory

Press and hold the BOOT button for more than 3 seconds to reset the board to factory defaults. You will have to provision the board again to use it.
