I watched your video, you obviously have a wiring error on the board or a fault on it. Connecting 5v should not cut the whole circuit I suppose that somewhere 5v and GND are connected. by a wire, a button, etc.
that 3 of the servos work I suppose this is probable if the board is only powered by the arduino.
check the vcc and v+ connections on the pin of the board
So i have downloaded this code and all servors work PCA9685-multiple-servo-control-using-Arduino-main.zip (854.1 KB)
maybe thgere is somthig wrong with the code ? i have downloaded twice to see i i saw any diference and still didnt work
just changed it stin only the first 3 servor
all of the other pin have graund to + 4.97v
ground to signal 383mv but it does not change when the section are opening and closing
but the first 3 do go down to 180mv
the stupidest thing we didn’t even think about it . you must define the pins in the dedicated page in aog. assign the function and position on the plate as you wish. in aog by default only the 3rd are defined
I intended to be the controller builder of a section myself, in principle I put everything as described above, but the system does not work correctly. The whole has a strange buzzing sound when I put it under power, and the servo motors don’t always work, it’s like there’s not enough voltage. Based on the points below, the default setting is 2.2 V for the servo motors and 3.7 V, which I think is not enough, what could be the problem, is the code wrong or is something wrongly connected? The DC-DC converter is set to 5 volts.
