<p>The Dual Button <a class="reference internal" href="../../Primer.html#primer-bricklets"><em>Bricklet</em></a> is equipped with
two buttons and can extend <a class="reference internal" href="../../Primer.html#primer-bricks"><em>Bricks</em></a>. Both buttons have a
built-in blue LED. You can read the current state of the button
(pressed/released) and of the LED (on/off). You can turn the LED on/off yourself
or enable auto-toggle. In auto-toggle mode the LEDs are toggled between on/off
with each button press.</p>
<p>It is also possible to use events. This allows to react to button presses
without polling.</p>

<p>To test a Dual Button Bricklet you need to have <a class="reference internal" href="../../Software/Brickd.html#brickd"><em>Brick Daemon</em></a> and
<a class="reference internal" href="../../Software/Brickv.html#brickv"><em>Brick Viewer</em></a> installed. Brick Daemon acts as a proxy between
the USB interface of the Bricks and the API bindings. Brick Viewer connects
to Brick Daemon. It helps to figure out basic information about the connected
Bricks and Bricklets and allows to test them.</p>
<p>Connect the Dual Button Bricklet to a <a class="reference internal" href="../../Primer.html#primer-bricks"><em>Brick</em></a>
with a Bricklet Cable.</p>
<p>If you connect the Brick to the PC over USB, you should see a new tab named
&quot;Dual Button Bricklet&quot; in the Brick Viewer after a moment. Select this tab.
If everything went as expected you can now see button presses and
change the state of the LED.</p>
<a class="reference external image-reference" href="../../_images/Bricklets/bricklet_dual_button_brickv.jpg"><img alt="Dual Button Bricklet in Brick Viewer" class="align-center" src="../../_images/bricklet_dual_button_brickv.jpg" style="width: 611.0px; height: 238.0px;" /></a>
<p>After this test you can go on with writing your own application.
