I am planning to build a motion sensing led for stairs, the total length of ws2812b led is 10m and total led is 600 (60 leds per meter). I am planning to use a 5v 40a ac to dc supply for both leds and Arduino. My question is will the Arduino Uno handle that current or should I use some workarounds.

[image] billava07: will the Arduino Uno handle that current Basic electronics. Given a 5V supply the Uno will only use as much current as it requires. You could use a supply capable of supplying 1000A and that would still be the case

Sure, will keep that in mind.
