PWM command

Hello,

I'm a beginner in Arduino project, but I want to pilot an PWM solenoid with a genuino card and a MOS transitor.

My solenoid is a 12V, and a current from 0 to 800mA, so my question is, is it possible to deliver this current with my configuration ?

Thank you for your help.

Hi

No. Absolutely not!

Arduino will supply 5V and max rated pin curren s 40ma. You will need an external 12V power supply to manage this. Also, don't connect the 12V supply to ANY of the Arduino pins. You can use a 12V PSU to power the Arduino though.

Hi, Welcome to the forum.

Can you please post a copy of your configuration circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

Thanks.. Tom.... :)

With the right mosfet and a connection to the right point on the power supply somewhere before the regulator on the UNO (assuming that can manage 12 volts an current to spare), it should work.
