Module 1 relay 5V for ARDUINO

The single channel 5V relay module for Arduino is used to control various devices with large power consumption.

To use a relay module, you must connect a controlled device to it. Then you need to connect 5V power supply to the VCC and GND terminals of the module. A microcontroller, computer or other control device is connected to the IN control terminal of the relay module.

The relay module has two interfaces - for connecting a control device (microcontroller, computer) and for connecting controlled devices to the relay:

A 3-pin interface is used to connect the relay module to the control device. GND and VCC pins for +5V connection, IN pin for control signal connection.
To connect controlled devices to the relay, there are 3 clamp contacts on the board. Designation of contacts NC, COM, NO (normally closed, common, normally open contact, respectively).
