How To Make a 5V Relay Module At Home and Check using Arduino One of the most useful things you can do with an  Arduino  is control higher voltage (120-240V) devices like fans, lights, heaters, and other household appliances. Since the Arduino operates at 5V it can’t control these higher voltage devices directly, but you can use a 5V relay to switch the 120-240V current and use the Arduino to control the relay. Pin details The relay module consists of six pins as a normally open pin, normally closed, common, signal, Vcc, and ground pins.  Signal Pin : It is used to control the relay. This pin can be active low or active high. In case of active low, the relay will activate when we apply an active low signal to the signal pin. On the contrary, in the case of an active high, the relay will activate when we apply an active high signal to the signal pin. But usually, these modules work on an active high signal. This signal will energize the relay coil to make contact with the common termina
