Sending a digital high or a "1" will trigger the relay.

The relay should have the positive wire of the device being used connected to "IN" and to "Out 1" as shown in figure 2, and any digital signal pin on the arduino end (For example pin 13). We recommend using a swappable cable to do this with, as using a relay requires you to perform some minor surgery on the appliance's cable.Ĭut and strip a portion of the positive wire so that you end up with two ends of the wire as shown in Figure 2. We will use "out1" for our example, using "out2" will simply reverse the logic, as explained above.

# This sample code is combined with the figure above to test the relay module whether works normally. (DO NOT CONNECT IT TO THE WALL WHILE MESSING WITH THE CABLE!) Test Connection Diagram Make sure the appliance to be tinkered with is unplugged from mains. WARNING: Please be very carful not to play with live circuits! 120V or 220V should not be taken lightly. NO(OUT2): Normally open, which means that when the relay is on (a digital high "1" is received from Arduino) the device is ON.

NC(OUT1): Normally closed, which means that when the relay is off (a digital low "0" is received from Arduino) the device is ON.

COM（IN）: input positive wire from appliance.

There are a total of 7 pins on the relay module board. The main difference between 16A Relay module and the old version relay module is the Max switching current.The max switching current of old version is 10A,and now the new version is 16A. It can be controlled through the digital IO port, such as solenoid valves, lamps, motors and other high current or high voltage devices. It can also be used to control the lighting, electrical and other equipments. The 16A relay module can be used in interactive projects. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. Gravity: 16A Relay Module For Arduino wiki- DFRobotĭigital 16A Relay Module is an electrically operated switch, which has a control system (also known as the input circuit) and the controlled system (also known as the output circuit), usually used in automatic control circuit.It is actually "automatic switch" ,using a small electric current to control a larger current.Therefore, the relay has the effects on the automatical automatic adjustment, security, conversion circuit in the circuit and so on.
