11+ 3 Pin Relay Wiring Diagram. Controlling a relay module with the arduino is as simple as controlling any other output as we'll see later on. Let us learn how to use one in our circuits based on the requirement of our project.
A relay is an electrically operated switch that can be turned on or off, letting the current go through or not, and can be controlled with low voltages, like the 5v provided by the arduino pins. Relays are most commonly used switching device in electronics. There are two colours shown.
So when wiring up these relays, the coil wire's will connect to pins 2 & 7 on the socket.
11+ 3 Pin Relay Wiring Diagram. Hello friends my name is. This pin also becomes the output pin out of the device and the detected infrared signal is carried this relay can be configured to be used with a electrical bulb or a tubelight please do the above shown wiring across all the pir modules, and then connect the shown 1,2,3 points together in parallel. Identify the hot power wire (red wire in the diagram above) in the cord leading to the light bulb and make a cut. This list covers single pole single throw (spst) relays, single pole double throw (spdt) the wiring diagrams below serve to show each pin of the relay and what they each represent, so a user can know how to wire them up when.
