I will apologise straight off for the lack of circuit diagram. But I will explain what I am trying to do as best as possible.
I have the dual altching relay model of this relay. I am trying to configure it so that I can both latch it either way with my arduino. A wise person on this forum has guided me to understand that in the diagram. I think 5v is applied to the + pin and then when setting or resetting the relay, I have to set either side to low? Is this correct?
I have also read that I should employ resistors and diodes to protect the arduino from getting fried.
Any help on how I would set this circuit up would be much appreciated. Thank you for your time.
