Now load the following program into the board. Which means the arm of the switch is connected between 4 and 6 by default and when a pulse is given to the relay the arm moved from 6 to 8, thus disconnecting 6 and connecting 4 to 8. I have a question and i’m not sure if your still monitering this post but i am using this exact same relay with an uno and i want to use it to controll an Hvac system so my question is if i am using the 2 leads from the hvac system and they need to be connected togather would it only be pin 1 and 16 that are connected to the arduino?

Among the three pins 4,6,8 4 and 6 are normally closed that is 4 is be default connected to 6 and when the triggering signal or pulse is given to pin1 the connection between 4 and 6 is broken.

Now load the following program into the board. Thus fhd27 have two relays in the HFD27 but both are controlled by the same trigger signal.

The pins 1 and 16 are the pins where we need to give the trigger pulse. The pins 1 and 16 are the pins where we need to give the trigger pulse. In the post we will see the basics of using the HFD27 relay using the Arduino uno board. Connect pin 16 and cathode of the LEDs to a common point and connect the common point to the ground pin on the Arduino board.
