 """
 This example shows how to use the ModulinoDistance class to read the distance from the Time of Flight sensor of the Modulino.
+
 The sensor works by sending out short pulses of light and then measure the time it takes for some of the emitted light to come back
 when it hits an object. The time it takes for the light to come back is directly proportional to the distance between the sensor and the object.

 """
 This example shows how to use the ModulinoKnob class to read the value of a rotary encoder knob.
+
 The knob is used to increase or decrease a value. The knob is rotated clockwise to increase the value and counter-clockwise to decrease it.
 
 You can register callbacks for the following events:

 """
 This example demonstrates how to use the ModulinoKnob and ModulinoBuzzer classes to play different notes using a buzzer.
+
 The knob is used to select the note to play. The knob is rotated clockwise to increase the frequency of the note and counter-clockwise to decrease it.
 Once the knob is pressed, the buzzer stops playing the note.
 Only the notes between 400 and 2000 Hz from the predefined list are played in this example.

 """
 This example shows how to use the ModulinoKnob and ModulinoPixels classes to control a set of pixels with a knob.
+
 The knob is used to set the number of pixels to turn on.
 The range property of the knob is used to map the knob values to the number of pixels to turn on.
