Questions about relays Answered
I am building a robot with a specific purpose and I have hit a snag. My remote controls on the receiver end are 4.5v and the motors I want to run are 12v all of it is DC. The relays I have don't pull in a 4.5v so I need another way to doing this. I either need another way of pulling in the relays; I need relays that pull in at 4.5, or some other intelligent solution that I cannot think of. Please help!
