I have a set of 4 240 to 24 V AC or 120-24 V DC relay.(mentioned on top) input it takes is 5 V from aurdino. I have a 12 V DC motor. How do I use this relay switch to run this 12 V DC motor. I have programmed my aurdino to work with relay and run the motor. The LEDs with the relay show the timing. I am confused how to run my 12V DC motor using the 24V relay

The 24v of the relay is just for the coil, the output terminal are for what ever you want to switch with them, IOW use a N.O. contact on the output terminals to switch 12v to your motor.
I presume you have some detailed information on the board itself??
