I need a design of a circuit for PCB board. The goal of the PCB board is to make 7 leds fade in / out in a short time (I will specify exactly ms of the cycle). At the same time I need to use a DFplayer integrated circuit to reproduce a sound from microSD. The LEDs and sound MUST be syncronized, and loop endless during the circuit has energy. Need to use 4x1,5V AA batteries = 6Volts.
I will provide more details later.
