 #### Controlling the LED Bar
 
-Alongside Servo 2040's six sensor headers are six addressable RGB LEDs. These work using the same chainable 1-wire signalling as WS2812 LED's, commonly known as Neopixels. As such, they can be controlled using the same Plasma Library used by the (Pimoroni Plasma 2040)[https://shop.pimoroni.com/products/plasma-2040].
