Smart Mirror

<h2>Project Overview</h2> <p>A DIY smart mirror that displays information like time, weather, and news. It uses a Raspberry Pi, a monitor, and a two-way mirror.</p> <h2>Bill of Materials (BOM)</h2> <ul> <li>Raspberry Pi (3 or 4)</li> <li>a monitor</li> <li>a two-way mirror film or acrylic sheet</li> <li>a PIR sensor for motion detection</li> <li>LED COB lights with a dimmer</li> <li>3D printed brackets</li> <li>and wood for the frame.</li> </ul> <h2>Circuit Diagram & Component Arrangement</h2> <p>Follow the wiring diagram below. Each component connects to specific pins on the microcontroller. Use a breadboard for prototyping and ensure all connections are secure before powering on.</p> <p><strong>Wiring Summary:</strong> The monitor connects to the Raspberry Pi via HDMI. The PIR sensor connects to the Pi's GPIO pins to trigger the display. LED lights are wired to a separate power supply and dimmer for backlighting.</p> <p><a href="https://www.instructables.com/How-to-Build-a-Raspberry-Pi-Smart-Mirror/">View circuit diagram</a></p> <h2>Step-by-Step Procedure</h2> <ol> <li><strong>Step 1 - Prepare Components:</strong> Gather all components from the BOM. Inspect for damage and verify ratings.</li> <li><strong>Step 2 - Breadboard Layout:</strong> Place the microcontroller on the breadboard. Arrange components for clear wiring paths.</li> <li><strong>Step 3 - Power Connections:</strong> Connect VCC and GND first. Ensure proper polarity for polarized components.</li> <li><strong>Step 4 - Signal Wiring:</strong> Connect sensors and actuators per the wiring table. Double-check pin assignments.</li> <li><strong>Step 5 - Upload Code:</strong> Connect USB, load the sketch, and upload. Verify serial output if applicable.</li> <li><strong>Step 6 - Test & Calibrate:</strong> Power on and test each function. Calibrate sensors if needed.</li> <li><strong>Step 7 - Enclosure (Optional):</strong> Mount in a 3D-printed or custom enclosure for durability.</li> </ol> <h2>Safety Notes</h2> <ul> <li>Always disconnect power before making wiring changes.</li> <li>Use appropriate eye protection when soldering.</li> <li>Adult supervision is required for makers under 16.</li> <li>Do not exceed voltage ratings of components.</li> </ul> <h2>Code & Resources</h2><p><a href="https://www.diymachines.co.uk/how-to-build-a-smart-magic-mirror">Download code and schematics</a></p> <h2>Attribution</h2><p>Source: <a href="https://www.diymachines.co.uk/how-to-build-a-smart-magic-mirror">https://www.diymachines.co.uk/how-to-build-a-smart-magic-mirror</a>.
