A Smart home Gingerbread House. Complete with motion detector, rotating tree, fairy lights and off key Christmas songs.

Ingredients:

• Gingerbread house + industrial-strength adhesive if you are not that good at baking
• Arduino UNO
• Piezo Buzzer
• Digital RGB LED Strip
• PIR Sensor
• Servomotor
• Wires

Assemble as shown and upload the Github code. Merry X-Mas.
