+The arduino switch platform allows you to control the digital pins of your [Arduino](https://www.arduino.cc/) board. Support for switching pins is limited to high/on and low/off of the digital pins. PWM (pin 3,5,6,9,10, and 11 on an Arduino Uno) is not supported yet.
+
+To enable the Arduino pins with Home Assistant, add the following section to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+switch:
+  platform: arduino
+  pins:
+    11:
+      name: Fan Office
+      type: digital
+    12:
+      name: Light Desk
+      type: digital
+```
+
+Configuration variables:
+
+- **pins** (*Required*): Array of pins to use. The number corresponds with the pin numbering schema of your board.
+  - **name**: Name that will be used in the frontend for the pin.
+  - **type**: The type of the pin. At the moment only 'digital' is supported.
+
+The digital pins are numbered from 0 to 13. The available pins are 2 till 13. For testing purposes you can use pin 13 because with that pin you can control the internal LED.
