LED Eye Mask "Hitomi-chan"
I made a mask for Halloween. This mask has LED's eye and its mouth flashes red. This mask drops children there in fear.
Parts
- Horror Mask
- Tape LED Neopixel
Arduino Pro Mini 5V 16MHz
Electret Microphone Board
Red LED
Step1: Paint the Mask Black
I bought a mask and painted black with a spray.
Step2: LED Tape Processing
In order to paint the LED tape black, attach a masking tape to the light emitting part. I paint the LED black with a spray.
Attach the LED tape to the mask and wire it.
There are 68 LED cells. It is connected by one signal line.
Step3: Microphone Attachment
Attach the Electret Microphone Board and two red LEDs to the mouth of the back of the mask.
The red LEDs glow in response to the voice.
Step4: Overall Structure
Microcontroller (Arduino Pro Mini 5V 16MHz) controls LED tape, Electret Microphone Board, red LED.
Step5: Code
LED Eye moves to the right or left and blinks randomly. The Electret Microphone Board detects the voice and lights the red LED.

}Step6: Operation
The LED eye move, the mouth reacts to the voice and it glows red.
I can not wait for Halloween!
