Voice activated LED facemask connection instructions

Precautions:
When making a voice-activated lamp mask, please be careful during the welding of the circuit, so as not to burn your skin by the welding machine! Please connect the circuit correctly and choose a good charging treasure. Short circuit and poor current input of the circuit may cause accidents! The voice-activated light mask is to be attached to the face, so the choice of mask fabric is very important, please choose fire-resistant fabric! Finally, please ask the younger children to make the production accompanied by an adult.

Tools Needed:
Solder
Soldering iron
Fabric Glue or a Sewing Kit
Safety goggies
Tape
snips

Optional Useful Stuff
A heat shrink (electrical tape can make due in a pinch, but the heat shrink is nice)
A digital multimeter (for ensuring your connections are correct and your electronics work)
A soldering mat
Arduino Nano

Production
1. Install Library file: Open "Tools"-"Library Manager" in the Arduino development software, then search for Adafruit_NeoPixel, Adafruit_NeoMatrix, Adafruit_GFX_Library, and then install these three libraries



2. Select the development board as Arduino Nano, this is to choose the right.


3. Select the processor as ATmega328P(Old Bootloader), this is to choose the right.


4. Then select the port, this port should be the same as what you see in the device manager, so that you can burn the code into the development board.
