Max Leds control arduino nano

hello recently I am starting programing with fastled,
and I am trying to control my strip 5m 60leds per meter ws2812b
with Arduino nano, but if I am trying to do more than 200 less it's not working good,
and I am trying to understand why it's happened.
thanks for the help.

Three bytes of RAM per LED.
5m x 60 = 300 LEDs, so 900 bytes of RAM,minimum

Should be doable.

How are you powering everything ?

Show us a good schematic of your circuit.
Show us a good image of your ‘actual’ wiring.
Give links to components.

It's frustrating to spend time helping You to write the question, what facts are needed, code.

Hi, @naorsa
Welcome to the forum.

Please read the post at the start of any forum , entitled "How to use this Forum".

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
