I’ve connected everything properly but it works not quite the way I want it to. If so, what value would be good?
What is the power source?
Yes, get pins 3 and 7 corrected before damage occurs. Its not a brilliant idea as it can only sink current. The middle pin should go to the motor. Currently I am using a ohm gate input resistor, It is working fine.
I’ll experiment and see what happens. The drain and source are supposedly not connected if there is no gate voltage applied and thus the motor should not spin but it does spin I’ve connecting it correctly, just the standard way that is found all over the internet. My question is thus: What I certainly did not understand is the purpose of R2. Thank you for your answer I was thinking of ohms so I am way under the maximum you have given me.
IRF power Mosfet 12 volt motor gate resistance – Electrical Engineering Stack Exchange
This is here incase the arduino comes loose, or the wiring is bad it will default to off. Stop making this worse by giving the impression these cartoons are acceptable here. I don’t think it is a wiring problem. Floating MOSFETs are bad, and because the “on” control of the FET is essentially just a capacitor with very low capacitance, it is quite easy for it to float up and turn itself on. The Arduino’s 40mA output maximum per pin is not going to be an issue.
Should I keep increasing the Capacitor? Firstly, thank you for taking the time to help me here. Email Required, but never shown. Does that sound right? Is there a setting I need to implement so you can view the Google Books page? I quote from KyranF: I have a IRF power Mosfet driving a 12 volt motor. Do you have a NPN transistor ex: My motor is 12V rated and draws approx mA current when on full speed. Wawa on Jan 13, ,
