There are 48 RGB LEDs （24 IC） per meter, and you can control each LED individually!
this is the digitally-addressable type of LED strip. You can set the color of each LED's red, green and blue component
with 7-bit PWM precision (so 21-bit color per pixel). The LEDs are controlled by shift-registers that are chained up
down the strip so you can shorten or lengthen the strip. Only 2 digital output pins are required to send data down.
The PWM is built into each 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. This chip has built in 1.2 MHz high speed 7-bit PWM for each channel - that means it can do 21-bit color per LED
