[SOLVED] Can't "Engaged" Arduino

[faak]

Hi,

I have changed the /boot/config.txt, from dtoverlay=pi3-disable-bt to dtoverlay=disable-bt

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

[all]
dtoverlay=gpio-fan,gpiopin=14,temp=80000
enable_uart=1
dtoverlay=disable-bt

Code:

pi@ladylaura:~ $ ls -l /dev/serial0
lrwxrwxrwx 1 root root 7 ott 28 08:48 /dev/serial0 -> ttyAMA0

Yellow light still not blinking and i can't engaged the motor controller.

That's an image of it:

In the Serial window i can see ttyAMA0

Code:

pi@ladylaura:~ $ dmesg | grep uart

I have istalled Arduino IDE on raspberry. 

/dev/ttyACM0 receive or send some data (here a sample of some data):
