+# WS2812 Module
+
+## ws2812.write()
+Send GRB data in 8 bits to a WS2812 chain.
+
+#### Syntax
+`ws2812.writegrb(pin, string)`
+
+#### Parameters
+- `pin` any GPIO pin 0, 1, 2, ...
+- `string` payload to be sent to one or more WS2812 LEDs.
+  It should be composed from a GRB triplet per element.
+    - `G1` the first pixel's Green channel (0-255)
+    - `R1` the first pixel's Red channel (0-255)
+    - `B1` the first pixel's Blue channel (0-255)
+... You can connect a lot of WS2812 ...
+    - `G2`, `R2`, `B2` are the next WS2812's Green, Red, and Blue channel parameters
+
+#### Returns
+`nil`
+
+```lua
+g = 0
+r = 255
+b = 0
+leds_grb = string.char(g,r,b, g,r,b) 
+ws2812.write(2, leds_grb) -- turn two WS2812Bs to red, connected to pin 2
+```
+
+## ws2812.writergb()
+Send GRB data in 8bits to a WS2812 chain.
+
+#### Syntax
+`ws2812.writergb(pin, string)`
+
+#### Parameters
+- `pin` any GPIO pin 0, 1, 2, ...
+- `string` payload to be sent to one or more WS2812 LEDs.
+  It should be composed from an RGB triplet per element.
+    - `R1` the first pixel's Red channel (0-255)
+    - `G1` the first pixel's Green channel (0-255)
+    - `B1` the first pixel's Blue channel (0-255)
+... You can connect a lot of WS2812 ...
+    - `R2`, `G2`, `B2` are the next WS2812's Red, Green, and Blue channel parameters
+
+#### Returns
+`nil`
+
+#### Example
+```lua
+leds_rgb = string.char(255,0,0, 0,255,0, 0,0,255) 
+ws2812.writergb(2, leds_rgb) -- turn three WS2812Bs to red, green, and blue respectively
+```
