I'm new here and I'm a newbie in electronics. Since 1 year I'm playing around with Arduino (different types) and now I want to build my own thing: a smiley with WS2812D-F5 RGB leds. But I'm not sure if I did any misstakes. Is it possible that an expert in electronics can check my schematic? That would be very kind, nice and cool :)
Functions: The switch SW1 is connected on D8 (PB4) and if pushed the smiley changes from sad to happy. pushed again it changes again and so on.
Because the WS2812 leds needs a lot of current, I have added some different possibilities to power the whole thing: 1x DC jack connected on a voltage regulator that output 5V fixed and two pins for a LiPo 3.7V that ist connected too on the voltage regulator. I dont know if it works if the LiPo has only 3.7V.
Well.. then I added a power switch, micro usb, FTDI and SPI connection. If one fails to burn the bootloader or to upload a sketch, I have more possibilities to do that ;)
Yeah I think thats it. If I forgot something, just ask me. Thanks a lot!

Edit 15.5.19 18:00 Ok, I just changed the schematic based upon your great advices :) Thanks a lot to everyone. I changed/added the regulator. Current output=3A (each one). Should be enough. But I'm not sure if I can divide the current in that way.
What do you think? :)
Greetings to everyone :)
