SK9822/APA102C LED Strip are 5050-sized LEDs with a smart IC Driver inside the LED.
You can set the color/brightness of each LED to 24-bit color (8 bits each red green and blue).
Each LED acts like a shift register reading incoming color data on the input pins
and then shifting the previous color data out on the output pin.
By sending a long string of data you can control an infinite number of LEDs just tack on more or cut off unwanted LEDs at the end.
The PWM is built into each LED-chip so once you set the color you can stop talking to the strip and it will continue to PWM all the LEDs for you

SK9822/APA102C Smart lamp is not same as the SK6812 smart led lamp.
It has double data sending (in and out) a clock pin and a data pin.
