## Build and Flash

Build the project and flash it to the board, then run the monitor tool to view the serial output:

* Run `source <directory with ESP-IDF version>/export.sh` to set IDF environment
* Run `idf.py set-target esp32c3` to set target chip
* Run `idf.py build` to build the project
* Run `idf.py flash monitor` to flash and monitor the project

(To exit the serial monitor, type `Ctrl-]` (or on a Mac `Ctrl-Option-6`).

See the Getting Started Guide for all the steps to configure and use the ESP-IDF to build projects.
