Overview
|
|
|
|
|
********
|
|
|
|
|
|
|
|
|
|
This is simple example demonstrating how to use a piezo buzzer connected
|
|
|
|
|
to port P0 on the edge connector of the BBC micro:bit board. Note that
|
|
|
|
|
the buzzer is not part of the main micro:bit board, rather it it needs
|
|
|
|
|
to be separately acquired and connected. A well working 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.
