The `arduino` sensor platform allows you to get an numerical values from an analog input pin of an [Arduino](https://www.arduino.cc/) board. Usually the value is between 0 and 1024. 

To enable an Arduino sensor with Home Assistant, add the following section to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
sensor:
  platform: arduino
  pins:
    1:
      name: Door switch
    0:
      name: Brightness

```

Configuration variables:

- **pins** array (*Required*): Array of pins to use.
  - **[number]** (*Required*): The pin number that corresponds with the pin numbering schema of your board.
    - **name** (*Optional*): Name that will be used in the frontend for the pin.

The 6 analog pins of an Arduino UNO are numbered from A0 to A5.
