That means the relay electromagnet is directly powered from the arduino's power pin, so the relay module and the arduino circuits are not physically isolated from each other (this is.
A wide variety of relay circuits schematics options are there are 28 suppliers who sells relay circuits schematics on alibaba.com, mainly located in asia. All four relays are connected with arduino at 8,9,10 and 11th pins (in1, in2, in3, and in4), and 1 12v adapter is used for powering the circuit. The second diagram shows the reverse potential due to the back emf, when the current is abruptly turned off. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using.
