 Blinking an LED
 ---------------
 
-This sketch shows the simplest case of digital out. Connect an LED in series with
-a 470ohm resistor between P8_07 and ground. The led is blinked on and off by 
-setting the digital pin `HIGH` and `LOW` every interval seconds (set it in the 
-`render()` function).
+This sketch shows the simplest case of digital out. 
 
-Firstly the pin mode must be set to output mode: 
-`pinModeFrame(context, 0, P8_07, OUTPUT);` in the `setup()` function. The output 
-of the digital pins is set by the following code: 
-`digitalWriteFrame(context, n, P8_07, status);` where status can be equal to

+In `setup()` the pin mode must be set to output mode via `pinModeFrame()`. For example: 
+`pinModeFrame(context, 0, P8_07, OUTPUT)`. 
+In `render()` the output of the digital pins is set by `digitalWriteFrame()`. For example: 
+`digitalWriteFrame(context, n, P8_07, status)` where `status` can be equal to 
 either `HIGH` or `LOW`. When set `HIGH` the pin will give 3.3V, when set to 
 `LOW` 0V.
 
 To keep track of elapsed time we have a sample counter count. When count reaches 
 a certain limit it switches state to either `HIGH` or `LOW` depending on its current
