 # 01_led-button

-This example is largely adapted from those in [ESP32-basic-starter-kit.pdf](./ESP32-basic-starter-kit.pdf).
-
-The APIs in the original examples paired with this PDF have changed, and I decided to do some different things with the code and/or circuits, but the original code can be [found here](https://www.dropbox.com/scl/fo/6znlij3eb23ih4jxcpv2w/AKvB1t9CCUgoVRVtGen8Yrw?rlkey=z84anl0hs940qf9fpl7l8q8q2&e=1&dl=0).

-There is no schematic for this example, it simply prints some output to the serial monitor at 115200.
+There is no schematic for this example, it simply prints some output to the serial monitor.
 This is more of a build system example for untethering yourself from the Arduino IDE.

 To build this example you can run the following commands.

 ```bash
-# See Dependencies section below for instructions.
-source ~/path/to/esp-idf/export.sh
-
 mkdir build
 cd build
 cmake ..
 make -j $(nproc)
-
-# Flash the example to the ESP.
-make flash
-
-# Check the serial monitor for 'Hello world!' output.
-idf.py monitor -b 115200
 ```

 To flash to your ESP or access the `idf.py menuconfig` menu from the ESP-IDF you can run the same commands with `make`.

 ## Dependencies

-Install the [ESP-IDF](https://github.com/espressif/esp-idf?tab=readme-ov-file#setup-build-environment)
+The [Arduino IDE](https://github.com/arduino/arduino-ide) must be installed.
+
+ install [ESP-IDF](https://github.com/espressif/esp-idf?tab=readme-ov-file#setup-build-environment)

 ```bash
-# https://docs.espressif.com/projects/esp-idf/en/v5.3.2/esp32/get-started/linux-macos-setup.html#for-linux-users
-sudo apt-get install -y git wget flex bison gperf python3 python3-pip python3-venv cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0

+git clone -b v5.3.2 git@github.com:espressif/esp-idf.git
 cd esp-idf
 ./install.sh
+
+# You only need to do this if you want to use ESP-IDF's idf.py helper script.
+# This example uses cmake, so it's not required.
 . ./export.sh
 ```

-In CLion there is an official [Serial Monitor](https://plugins.jetbrains.com/plugin/8031-serial-port-monitor) plugin, or use ESP-IDF -

-```bash
-idf.py monitor -b 115200

-## Starting Over
-
-To set up this project from scratch the following commands were used
-
-```bash
-# My example project directory
-cd ~/Code/klips/esp/cpp/04_esp-idf-arduino
-idf.py set-target esp32
-idf.py add-dependency "espressif/arduino-esp32^3.1.1"
-
-# Autostart Arduino for use of `loop()` and `setup()` functions
-# You can also use the esp-idf `app_main()` function if preferred
-# https://docs.espressif.com/projects/arduino-esp32/en/latest/esp-idf_component.html#configuration
-# You can alternatively do this in the GUI tool `idf.py menuconfig`
-echo "CONFIG_AUTOSTART_ARDUINO=y" >> sdkconfig
-sed -i -e 's/CONFIG_FREERTOS_HZ=100/CONFIG_FREERTOS_HZ=1000/' sdkconfig
-
-# Build the project
-idf.py build
-```

-# 05_temp-humidity-web
-
-This is the same example in [03_temp-humidity-web](./../03_temp-humidity-web), ported to the cmake ESP-IDF build system.
-
-For instructions on setting up the ESP-IDF see [04_-esp-idf-arduino](./../04_esp-idf-arduino)
-
-This example is largely adapted from those in [ESP32-basic-starter-kit.pdf](./ESP32-basic-starter-kit.pdf).
-
-The APIs in the original examples paired with this PDF have changed, and I decided to do some different things with the code and/or circuits, but the original code can be [found here](https://www.dropbox.com/scl/fo/6znlij3eb23ih4jxcpv2w/AKvB1t9CCUgoVRVtGen8Yrw?rlkey=z84anl0hs940qf9fpl7l8q8q2&e=1&dl=0).
-
-![schematic](./schematic.png)
-
-Temperature and humidity sensor served on a web page within the local network.
-
-![screenshot](./screenshot.png)
-
-To build this example run the following commands.
-
-```bash
-source ~/path/to/esp-idf/export.sh
-
-mkdir build
-cd build
-cmake ..
-make -j $(nproc)
-make flash
-```

-Examples 1-3 are built using the Arduino IDE.
+This directory contains ESP32 projects largely adapted from the examples in [ESP32-basic-starter-kit.pdf](./ESP32-basic-starter-kit.pdf).

-All examples after `04_esp-idf-arduino` are built with cmake and the [ESP-IDF](https://github.com/espressif/esp-idf).
+The APIs in the original examples paired with this PDF have changed, and I decided to do some different things with the code and/or circuits, but the original code can be [found here](https://www.dropbox.com/scl/fo/6znlij3eb23ih4jxcpv2w/AKvB1t9CCUgoVRVtGen8Yrw?rlkey=z84anl0hs940qf9fpl7l8q8q2&e=1&dl=0).

+The board selected in [Arduino IDE](https://www.arduino.cc/en/software) is ESP32 Dev Module -
