thank all of you for your answers
I reformulate my question or my problem,
I want to control a strip of rgb led individually addressable as this type of led
I want to make a matrix of 11 columns and 6 rows and i will scan a barcode that will give me the position of the led and I must light on this led with red or green according to a specific situation.
Ive made a test with normal RGB LED without problem but i will be limited by arduino pins that's what pushed me to think about the solution of RGB Strip led ws2811.
I also thought to Shift register 74HC595N there too I wonder if it's possible to control leds individually
Thank you so much for your help
