The same it true for the pins 13,11 and 9 respectively.

Posted by Tux Think at 4: In the post we will see the basics of using the HFD27 relay using the Arduino uno board. 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 005-x signal or pulse is given to pin1 the connection between 4 and 6 is broken.

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.

Thus we have two relays in the HFD27 but both are controlled by the same trigger signal. 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.

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. The same it true for the pins 13,11 and 9 005.

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 005-e or pulse is given to pin1 the connection between 4 and 6 is broken. A relay is used to connect or disconnect a circuit based on a trigger signal.
