 The six LEDs are connected to six digital-out pins. As the volume varies between 0% and 100% of the sensor'​s range, it outputs a value between 0 and 100. This value is read in the same algorithm as analog input A0 was read before and the amount of lit LEDs corresponds to the output of the sensor. The six LEDs are connected to six digital-out pins.
