-This test code shows how to configure GPIO and how to use it with interruption.

-## GPIO functions:
-
-| GPIO                         | Direction | Configuration                                          |

-| CONFIG_GPIO_OUTPUT_1         | output    |                                                        |
-| CONFIG_GPIO_INPUT_0          | input     | pulled up, interrupt from rising edge and falling edge |
-| CONFIG_GPIO_INPUT_1          | input     | pulled up, interrupt from rising edge                  |
-
-## Test:
- 1. Connect CONFIG_GPIO_OUTPUT_0 with CONFIG_GPIO_INPUT_0
- 2. Connect CONFIG_GPIO_OUTPUT_1 with CONFIG_GPIO_INPUT_1
- 3. Generate pulses on CONFIG_GPIO_OUTPUT_0/1, that triggers interrupt on CONFIG_GPIO_INPUT_0/1
-
- **Note:** The following pin assignments are used by default, you can change them by `idf.py menuconfig` > `Example Configuration`.

-## How to use example
-
-Before project configuration and build, be sure to set the correct chip target using `idf.py set-target <chip_name>`.
+This is the code for my prototype automated plant watering system, which uses two pumps to automatically water my plants, and also monitors the ambient humidity and temperature.
 
 ### Hardware Required
