Hey guys, I'm working on a project to get keyless drive working in my golf cart. I currently am using an Arduino with a PN532 shield to recognize the tag, and output a 5V signal from the Arduino. My problem is actually enabling the motor once the tag is sensed.
I've been trying to decide if I should use some type of relay to take the 5V and close the relay contacts, but I've had trouble finding a relay that takes 5V to power it but can handle the 48V that my golf cart batteries are run at.
Does anyone else have any experience with anything like this? I feel like I'm missing something obvious. Thanks for the help.
