+# NeoPixel driver
+
+This library provides a driver for various Neo Pixel LED strips, 
+see https://www.adafruit.com/category/168
+
+NeoPixels consist of a number of RGB LEDs, every one of them controlled
+separately.  
+
+## Basic usage
+
+```
+// Create a NeoPixel driver - specify the number of LEDs:
+let strip = neopixel.create(24)
+
+// set pixel colors
+strip.setPix(0, 255, 255, 255) // white
+strip.setPix(1, 255, 0, 0)     // red
+strip.setPix(2, 0, 255, 0)     // green
+strip.setPix(3, 0, 0, 255)     // blue
+
+// send the data to the strip
+strip.display()
+```
+
+Use `strip.setPin()` if your strip is not at `P0`.
+
+Use `strip.setBrigthness()` to lower the brightness (it's maxed out by default).
+
+Use `strip.shift()` or `strip.rotate()` to shift the lights around.
+
+## Example: Using accelerometer to control colors
+
+This little program will let the position of the microbit control the color of the first LED.
+This first LED will then get shifted further away every 100ms.
+
+```
+let strip = neopixel.create(24)
+while (true) {
+    let x = input.acceleration(Dimension.X) / 2
+    let y = input.acceleration(Dimension.Y) / 2
+    let z = input.acceleration(Dimension.Z) / 2
+    strip.setPix(0, x, y, -z);
+    strip.shift(1);
+    strip.display();
+    basic.pause(100);
+}
+```
