There are 60 RGB LEDs 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 8-bit PWM precision
(so 24-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 1 digital output pin are required to send data down. 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
