3 Float/Reed Switches Controlling a 16 Pixel RGB LED Ring via UNO Answered

Good evening,

My latest project is for a level indicator on my chicken coops water supply.  I am using an Arduino UNO, 3 reed float switches and a 16 pixel RGB LED Ring (adafruit Neopixel).  I have the switches at 3 different positions in the water tank. I am wanting to light the RGB LED ring a different colour depending on which switch is closed.  The bottom one red, the middle orange and when at the top, green.

I have the LED ring working.  I also can have the switch working on its own.  But not controlling the LED.
I have no idea what to do next.  I am thinking that i need to get the switch turning the LEDs on.  Then I can start thinking about using all three at once.

I am hoping someone can help?  It seems a simple task for the arduino to do but I am very new at this so I'm struggling a little bit.

Thank you all in advance.

You are already using a computer for this so I somehow fail to see the problem !?
Three inputs, three outputs, which really equals to just a few lines of code.
Do it fancy with some IF statements so only one LED will be one at any given time.

I'm using a LED Pixel. I have got it working with 3 separate LEDs but wanted to use one of these (Pic below).

Sorry again, but I still fail to see the problem as the code libraries can be downloaded from Adafruit.
Simply adapt your 3 LED code for the neopixel library, examples should be included....
