6(See the README.md file in the upper level 'examples' directory for more information about examples.)
7
8RMT peripheral can send customized RMT items in a loop, which means we can use it to generate a configurable length of periodic signal.
9
10This example will show how to drive a passive buzzer to play a simple music, based on the RMT loop feature.

39### Build and Flash
40
41Run `idf.py -p PORT flash monitor` to build, flash and monitor the project.
42
43(To exit the serial monitor, type ``Ctrl-]``.)
44
45See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.
