Constitution
LED is light when it detects a certain degree of amplitude picked up the sound with a microphone , and around a small motor .
Parts List
- Motor driver module DRV8830
- The motor for the vibrating motor LA4-466FB
- LED tape neopixel
- High sensitivity MIC amplifier kit
- Lithium-ion polymer battery 110mAh
- Adafruit Trinket 3.3 V
- 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!
