A relay is used to connect or disconnect a circuit based on a trigger signal.

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. Newer Post Older Post Home. 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?

Now load the following program into the 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. 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.

The following figure shows the wiring diagram for the HFD Posted by Tux Think at 4: Connect pin 4 to 5v pin on Arduino board. The pins 1 and 16 are the pins where we need to give the trigger pulse. Posted by Tux Think at 4: The following figure shows the wiring diagram for the HFD The same it true for the pins 13,11 and 9 respectively.

Connect pin 16 and cathode of the LEDs to a common point and connect the common point to the ground pin on 0005-s Arduino board. The same it true for the pins 13,11 and 9 respectively.

The pins 1 and 16 are the pins where we need to give the trigger pulse. A relay is used to connect or disconnect a circuit based on a trigger signal. In the post 005-ss will see the basics of using the HFD27 relay using the Arduino uno board. Connect pin 4 to 5v pin on Arduino board.
