&lt;hr /&gt;
&lt;div&gt;&lt;br /&gt;
&lt;br /&gt;
== Doorbell 2.0 ==&lt;br /&gt;
&lt;br /&gt;
Arduino-based, includes lights and a customizable tone.&lt;br /&gt;
&lt;br /&gt;
To do: mount in a stable enclosure.&lt;br /&gt;
&lt;br /&gt;
Troubleshooting&lt;br /&gt;
&lt;br /&gt;
 * Check that the speaker is connected to the green terminals of the arduino, and an audio cable is plugged into the intercom box by the top door.&lt;br /&gt;
 * Hit the reset key on the Arduino&lt;br /&gt;
 * Ring the door bell. Does it work?&lt;br /&gt;
 * Re-upload or modify the Arduino sketch&lt;br /&gt;
&lt;br /&gt;
If this fails you can revert to doorbell 1.0.&lt;br /&gt;
&lt;br /&gt;
Want to improve the doorbell? Change the chime? Here is [https://github.com/danasf/noise-/tree/master/doorbell arduino code].&lt;br /&gt;
&lt;br /&gt;
You&#039;ll need a USB mini cable to connect. The board is a [http://www.freetronics.com/products/etherten Freetronics Etherten], but choose Uno in the Arduino IDE. &lt;br /&gt;
&lt;br /&gt;
Improvements &amp;amp; ability to alter light and sound patterns via ethernet will be coming soon.&lt;br /&gt;
&lt;br /&gt;
== Doorbell 1.0 ==&lt;br /&gt;
&lt;br /&gt;
Via original intercom box.&lt;br /&gt;
&lt;br /&gt;
Fallback instructions.&lt;br /&gt;
&lt;br /&gt;
Go to the intercom box by the top door:&lt;br /&gt;
&lt;br /&gt;
 * Ensure the buzzer switch on the top is set to &#039;On&#039;&lt;br /&gt;
 * Unplug the audio cable from the side of the intercom box by the door.&lt;br /&gt;
Doorbell 1.0 functionality should work&lt;/div&gt;</summary>
