+## ws2801.write()
+Sends a string of RGB Data in 24 bits to WS2801. Don't forget to call `ws2801.init()` before.
+
+#### Syntax
+`ws2801.write(string)`
+
+####Parameters
+- `string` payload to be sent to one or more WS2801.
+  It should be composed from an RGB triplet per element.
+    - `R1` the first pixel's red channel value (0-255)
+    - `G1` the first pixel's green channel value (0-255)
+    - `B1` the first pixel's blue channel value (0-255)
+... You can connect a lot of WS2801...
+    - `R2`, `G2`, `B2` are the next WS2801's Red, Green, and Blue channel values
+
+#### Returns
+`nil`
