set Sound Threshold
Tell how loud it should be for your board to detect a loud sound.
input.setSoundThreshold(SoundThreshold.Loud, 0)
When the microphone hears a sound, it sets a number for how loud the sound was at that moment.
This number is the sound level and has a value from 0 (low sound) to 255 (loud sound). You can use
a sound level number as a threshold (just the right amount of sound) to make the
on sound event happen. To set a threshold, you choose the type of sound
to detect, loud or quiet, and then the sound level for that type.
~ reminder
This block requires the micro:bit V2 hardware. If you use this block with a micro:bit v1 board, you will see the 927 error code on the screen.
