Trigger motor using MOSFET

Community Projects

I have a project that uses a 12v motor which draws 4A under load, I have this working with the arduino and a relay.

I am a noob at electronics, but would like to swap out the relay with a MOSFET. I’ve read that I need to be looking for a logic level MOSFET with an RDS on value of 5v. Now there are masses to chose from. Can anyone help me with my selection please?

Thanks

Look at Adafruit’s tutorials (lessons) to learn about using MOSFET.

Did you search this forum for discussions on this? It has been posted before.

If you give us links to MOSFET data sheets of ones you think might work then we can help.
