Welcome, This is a sliding door secret compartment project. It has the look of a simple and inexpensive picture frame to throw any unwanted people off. With a push of a button the picture fame slides open/close.

The door is driven by a continuous rotation servo motor with a pulley system. There are two hidden push buttons that control the servo motor rotation. Inside the enclosure there is a Normally Open mini contact switch (NO), and 5 LEDS . As the door slides open the switch goes from normally open to close state, turning the LEDS ON. When sliding door closes, it turns the LEDS OFF, by changing the contact switch back to N.O state.

The circuit is a typical and simple servo motor driver/tester, using the 555 IC timer. This circuit works great with continuous rotation servos. I built this project using whatever parts were  handy and available that I could use at the time it was built.

There are a lot of features you can apply to this project, for example using a microcontroller like the Arduino to control a motion sensor, Clapping sensor, Wireless Remote, a camera that text you pictures when the door is been open, use an entry key pad code to activate the door. There are a lot of things you can add to this project, to make it more of a spy kind of gadget.

<p>whats in the bag?</p>
<p>AWESOME! I bet this will win 1st in the Secret Doors &amp; Compartment contest :D </p>
amazing! Great work.
that is awesome
<p>Love it!</p>
<p>Really well done. Good job :)</p>
<p>thats awesome</p><p>i want make like this but i would make a drawer </p>
<p>i like what looks to be a dent on the left side of the picture frame, lol. great instructable.</p>
<p>Can't wait to make this, got my vote(s)</p>
<p>Thank you for your vote (s).</p>
So cool
<p>Thank you.</p>
<p>Very cool!</p><p>I can't wait to build one.</p>
<p>Thank you, I'm adding a wireless remote control to operate the door. </p>
<p>That's pretty cool!</p>
<p>Thank you</p>
