+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).

+# 02_led-button-web
+
+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)
+
+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).

+
+## 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
+```
