Re: esp32 motor stepper 35BYJ412

Hi neo888, I remember having issues controlling similar motor until I checked the specification for exact sequence the motor coils should be energised. A more common stepper motor driving method is "full step" where 2 of the 4 coils are powered at each step. This motor should be powered in "half ste...

Hi newhobby,

Please check example player / pipeline_sdcard_mp3_control/. It demonstrates how to play several mp3 files without destroying the pipeline.
