I am quite new to this forum so I do not know if this is the right thread to post about my problem.
Anyway, I am trying to control 144 WS2812B LED using an Arduino nano.
To wire my circuit, I followed the attached schematics.
However, when the LED are above 80% of their full power, they draw about 1.3 Amps or more. When measuring the voltage coming to the Arduino, my multimeter reads 3,5 volts.
Therefore, I guess the Arduino freezes because the voltage gets too low.
I must say that I am using a 5 Amp power supply unit so power should not be a problem here (from my understanding).
I hope this is clear enough for you to understand my problem. Does anyone have an idea to fix my problem ?
