Please put in the vicinity of the radio and speaker .
Figure to be lip-synching to the music is very cute .
I hope you enjoy it !
Step 1: Material
- Arduino Pro mini 3.3v/8Mhz （Arduino Pro mini has a 4 pin.）
- 8 x 8 Led Matrix (32mm x 32mm)
- Sound Sensor Detection Module LM393 Chip Electret Microphone For Arduino
- USB cable
- LED Gradation Light (100 yen shop)
LED Gradation Light contains a 1.5V × 3 pieces of battery .If you do not use the USB cable is connected to the battery .
Step 2: Cut the USB Cable
Step 3: Check the Power Supply of 5V
You check with a tester that the 5V can be taken from the USB cable .
Step 4: To Make a Hole
Step 5: You Pass Through the USB Cable Into the Hole .
Step 6: Ｆixed With a Binding Band.
Step 7: Pull Does Not Come Off Also .
Step 8: Give Power to the Arduino.
USB 5V（+） to Arduino RAW
USB GND(-) to Arduino GND
Step 9: Connect the Microphone
Microphone +5V to Arduino VCC.
Microphone OUT to Arduino A4.
Microphone GND to Arduino GND.
Step 10: Replace the LED Matrix
It is very difficult.
Please to solder by bending the legs of the LED matrix as shown in the photograph .
Please note the position of the LED matrix of projection .
Step 11: Solder Is Difficult
Step 12: You Can Press the Case Put the LED Matrix .
Step 13: Sketch
Step 14: Attach Paste the Double-sided Tape on the Back of the Microphone
Step 15: Done!
Please try to adjust the microphone when the face does not change .
It defines the facial animation in the first part of the sketch .
