Arduino 4 Relay Module Wiring

Controlling a relay module with the arduino is as simple as controlling any other output as we ll see later on.

Arduino 4 relay module wiring. Alasan menggunakan power supply eksternal dikarenakan agar arus pada arduino nano tidak drop yang hanya sebesar 500ma. In4 black pin 10. The connections for connecting the relay module with arduino are very simple. In2 red pin 12.

In this example we will connect the relay module with arduino in the normally open state. More information and instructions can be found on my blog. The light bulb has one of the 120v wire spliced to connect the end connected to the power plug to the com common pin of the relay module and the one going to the lamp is connected to the nc normally closed pin. Gnd yellow gnd.

In this example we will take a look at another relay module this time this one is called the 5 volt 4 channel arduino relay module here is a picture of the module. This relay module provides four relays that are rated for 7a at either 28vdc or 10a at 125vac. A relay is an electrically operated switch that can be turned on or off letting the current go through or not and can be controlled with low voltages like the 5v provided by the arduino pins. In3 brown pin 11.

Vcc white 5v for in1 to in4 you can use any pins 2 to 13 or a0 to a5 on arduino board but you have to remember which pin control each relay line to setup code properly. Then connect the signal pin of the relay module with the pin 12 of the arduino. In1 orange pin 13. Introducing the relay module.

We connect the ir motion sensor out to pin 4 and the relay in1 to pin 8. So connect the 5v and the ground of the arduino with the 5v and the ground of the relay module. Relay output 1 2 4 8 way relay module for arduino ksh 299 00 ksh 907 00 relays are switches that open and close circuits electromechanically or electronically. This 8 channel relay module can adopt most common range of microcontrollers such as arduino raspberry pi avr pic arm with digital outputs to control larger loads devices like ac or dc motors electromagnets soleniod incandescent light bulbs actuators and any another devices that you want to drive with in the relay.

Pada saat penekanan 9 16 maka relay 1 relay 8 akan off satu persatu secara berurutan. Power supply 12vdc 2a. Connect wires from relay module to arduino pins. Each relay has a normally open no and a normally closed nc contact.

Nc pin is connected to the com pin by default unless you send a signal from the arduino to the relay module to break the connection.
