+
+This directory contains a `CMakeLists.txt`, which can be selected to open as a 
+project within your preferred IDE. From there, all nested examples can be built,
+debugged, and ran.
+
+The plugin examples will need to be installed for Qt Designer integration to work.
+On Linux, Qt Designer looks under `/some/path/to/Qt/Tools/QtCreator/lib/Qt/plugins/designer/`.
+On windows or Mac, this path may differ. Unfortunately I don't have these machines to test for myself.
+
+```bash
+cd klips/cpp/qt/designer-plugin-collection
+mkdir build && cd build
+cmake .. && cmake --build . --target install
+```
+
+After installing the plugin collection example above, we can open Qt Creator and navigate to the Designer.
+We should see the custom collection is available within the Designer, and the contents of the widgets render correctly in the application view.

+This example uses the same schematic as [01_led-button](../01_led-button/).
+
+The only difference is that you can also control the button through a web browser from any device connected to your local network.
+
+This example was adapted from the example code in the [Arduino ESP32 API reference](https://docs.espressif.com/projects/arduino-esp32/en/latest/api/wifi.html#wi-fi-ap-example).

+
+Temperature and humidity sensor served on a web page within the local network.
+
+![screenshot](./screenshot.png)
+
+## Dependencies
+
+You need to install a couple of libraries for this project:
+
+* The DHT and the Adafruit Unified Sensor Driver libraries to read from the DHT sensor.
+* ESPAsyncWebServer and Async TCP libraries to build the asynchronous web server.
+
+The default Arduino IDE installation will store libraries at `~/Arduino/ibraries` - if this directory doesn't exist, create it.
+
+### Installing DHT Sensor Library
+
+To read from the DHT sensor using Arduino IDE, you need to install the [DHT sensor library](https://github.com/adafruit/DHT-sensor-library).
+
+```bash
+wget -O DHT_sensor.zip https://github.com/adafruit/DHT-sensor-library/archive/master.zip
+unzip DHT_sensor.zip
+mv DHT-sensor-library-master/ ~/Arduino/libraries/DHT_sensor
+```
+
+## Install Adafruit Unified Sensor Driver Library
+
+You also need to install the [Adafruit Unified Sensor Driver library](https://github.com/adafruit/Adafruit_Sensor) to work with the DHT sensor.
+
+```bash
+wget -O Adafruit_sensor.zip https://github.com/adafruit/Adafruit_Sensor/archive/master.zip
+unzip Adafruit_sensor.zip
+mv Adafruit_Sensor-master/ ~/Arduino/libraries/Adafruit_sensor
+```
+
+## Installing ESPAsyncWebServer Library
+
+Follow the next steps to install the [ESPAsyncWebServer library](https://github.com/me-no-dev/ESPAsyncWebServer):
+
+```bash
+wget -O ESPAsyncWebServer.zip https://github.com/me-no-dev/ESPAsyncWebServer/archive/master.zip
+unzip ESPAsyncWebServer.zip
+mv ESPAsyncWebServer-master/ ~/Arduino/libraries/ESPAsyncWebServer
+```
+
+## Installing Async TCP Library
+
+The ESPAsyncWebServer library requires the [AsyncTCP library](https://github.com/me-no-dev/AsyncTCP) to work. Follow the next steps to install that library:
+
+```bash
+wget -O AsyncTCP.zip https://github.com/me-no-dev/AsyncTCP/archive/master.zip
+unzip AsyncTCP.zip
+mv AsyncTCP-master/ ~/Arduino/libraries/AsyncTCP
+```

+# 03_temp-humidity-web
+
+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
+mkdir build
+cd build
+cmake ..
+make -j $(nproc)
+```
+
+To flash to your ESP or access the `idf.py menuconfig` menu from the ESP-IDF you can run the same commands with `make`.
+
+```bash
+make flash
+make menuconfig
+```
+
+If Ninja is preferred:
+
+```bash
+mkdir build
+cd build
+cmake .. -G Nina
+ninja
+```
+
+## Dependencies
+
+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
+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
+```
