This is voice-activated Patrol Lamp. It have mic and sense voice. While sensing the voice, the lamp operate.

Constitution

LED is light when it detects a certain degree of amplitude picked up the sound with a microphone , and around a small motor .

Trinket Battery Module

Device

PET bottle cap with a light-shielding plate to the motor fixed , it rotates around the LED.

Fix the plastic bottle cap with a light-shielding plate on the motor and

Rotate the LED tape around the center.

Arduino Code

The microcomputer adafruit trinket used is small and convenient!
