I have a 24-ring RGB LED connected to an Arduino, which is powered by a 3.7V battery, with an MT3608 boosting the voltage to 5V for the Arduino. On the other side, I have a Bluetooth audio module directly connected to the 3.7V battery. When I turn on the LEDs to white, the system becomes unstable and the audio module shuts down. How can I solve this issue?

Which Arduino do you have ?
Are the 24 LEDs being powered directly from the Arduino ?

i have nano . Yes LEDs directly connected to arduino.
The Arduino is not designed to be a used as a power supply in that way. How much current do the LEDs take when at full white brightness ?

on white color full brightness the current is 1440mA.
i've connected LEDs vcc pin to directly 3.7v battery and it looks good for now thank you for help.
I am glad that you saw what I was getting at and fixed it

The MT3608 I found has 2 ampere output capacity.
You could power the strip at 5 volts as it is probably designed for directly from the boast regulator.
