| 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. |

| Building |

| |
| The sample can be built as follows: |

| 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. |
