+homeassistant.components.switch.arduino
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Support for switching Arduino pins on and off. So fare only digital pins are
+supported.
+
+Configuration:
+
+switch:
+  platform: arduino
+  pins:
+    11:
+      name: Fan Office
+      type: digital
+    12:
+      name: Light Desk
+      type: digital
+
+Variables:
+
+pins
+*Required
+An array specifying the digital pins to use on the Arduino board.
+
+These are the variables for the pins array:
+
+name
+*Required
+The name for the pin that will be used in the frontend.
+
+type
+*Required
+The type of the pin: 'digital'.
