Making a Remote Control

Projects General Guidance
1

I did posted this before but it wasn't very constructive because I lacked information at the time. Hopefully I have everything now. I need help, I am new to Arduino and I want to make sure I don't spend the money and turns out that I did something wrong/it wont be able to work.

I want to make a remote control Arduino to turn a motor on and off. It is a power window motor (the one you use for your car) and it is being powered by a car battery. I want to turn it on and off, that simple.

This is what I am using for the remote.

This is the relay

There isn't a max voltage that can go through that relay, right? Do I understand this correctly? Will this work or am I going to mess up my board?

There are limits to the relay contacts. Those limits are displayed on the relay case. For DC voltage it appears to be a maximum of 10 Amps and a maximum of 28 Volts.

You will need a transistor to drive the relay since, I believe, they draw more than 40 mA.

So you only need to drive the motor in one direction? Just ON or OFF?
