3 phase Invertor controlling

Good afternoon!

With an eye on the inverter for a 3-phase motor, I assembled such wiring diagram.

So far, I decided to connect one shoulder (just open transistors 4 and 3) and on the LED

Do you think it is necessary to put more resistors between the arduino output and the input to the driver? Is the scheme viable at all?

From your picture I would say no. A proper annotated schematic instead of the fuzzy picture would be a big improvement. You mentioned a shoulder of a transistor, I have never come across that before or do I see any transistors in your picture. I have no idea what the blue and red things are but I see P-Channel MOSFETs with no idea of how they are controlled. Links to "Technical" specifications on the motor etc would help us help you. More information needed.

Impossible to tell, given the useless Fritzing-type diagram. Please post a genuine schematic diagram.

Sorry. Only such image. Module IRF 520 usually sold for Arduino applications. Now I just want to on the LED as an first step.

And unfortunately, it does not work with Arduino, as the IRF520 requires 10V on the gate to be turned fully on.

A 3 phase inverter is not a beginner project.

The IRF520 is far from the best choice. You take your gas guzzler to a gas station and put kerosene in the gas tank as that is all they had, so you filled it but will it operate properly? You are asking questions that cannot be properly answered without the needed information. Do not forget the Schematic and links to "Technical" information on the devices. You only want to drive a LED. Put it in your car and drive around, that is about as accurate as I can give without knowing technical information about the LED. Datasheet links give that information.

I use the driver
