The `arduino` sensor platform allows you to get 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 %}
|
