Overview
|
|
********
|
|
|
|
This sample demonstrates how to use a piezo buzzer connected
|
|
to port P0 on the edge connector of the BBC micro:bit board.
|
|
|
|
Requirements
|
|
************
|
|
|
|
A separate piezo buzzer connected to the board. One example is the MI:Power
|
|
board that has a piezo buzzer in addition to a coin-cell battery. Resellers of
|
|
this board can be fairly easily found using online search.
|

Sample Output
|
|
=============
|
|
|
|
This sample outputs sounds through a connected piezo buzzer based on
|
|
button presses of the two main buttons. For each press the current
|
|
output frequency will be printed on the 5x5 LED display.
