Squid Game LED Mask

I made mask by using 12V LED strip.

First take a cardboard draw the shape of mask as per your face size

Now paste led strip in square shape

and then make the circuit as per the schematics

After the making the circuit now upload the program

Before uploading remove the TX and RX pin of HC-05 bluetooth module

After uploading insert the TX and RX pin again

Now open install the bluetooth app

Now open the bluetooth option click on hc-05

Enter the password 1234

After pairing

Now open the bluetooth app

Click on LED Bluetooth

Now select HC-05 again

Now you can control your led strip by using your smartphone
