If you want to switch a device with a high current or voltage requirement on and off, whether with direct current or alternating current, you need a relay. A relay is an electronic switch that is activated by a signal we send from an Arduino (or a compatible board like Dasduino). This module further simplifies the whole process as it contains everything you need for the relay and you only need to connect it to the microcontroller and the power supply. You don't even have to worry about voltages and currents, isolation between high and low voltage or grounding as everything is already accounted for on the board.
