Smartbread

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

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

Assemble as shown.

Upload the code to your Arduino.
