39+ Arduino 5V Relay Module Schematic Gif. A relay can be used to control high voltages with a low voltage by connecting it to an mcu. So we can see that the 5 volts from our microcontroller the arduino's 5v pin will be connected to the vcc pin of the module and the pin number 7 to the in1 input pin for controlling the relay.
