Whether operating on \u003cstrong\u003eDC\u003c\/strong\u003e or \u003cstrong\u003eAC\u003c\/strong\u003e, a relay is what you need.\u003c\/p\u003e\n\u003cp\u003eA relay is actually an electronic switch that is activated by a signal we send from a microcontroller. This module further simplifies the whole process because it contains everything you need for the relay to work, and you just have to connect it to the microcontroller and power supply. You don't have to think about voltages and currents, insulation between high and low voltage or grounding, everything is already taken care of on the board.
