4 Arduino Relay Module 5V / 12V Relay Control Module With Demo Code

4-channel relay module relay module expansion 5V or 12V for arduino with demo code Arduino Relay Module

 

 

Description:

 

1.The input signal can be 3.3 V 5 V

2.Are low level effective. Support 3.3V 5 V

3.It has jump line. Can set high and low level

4.The power source and the relay system power can be divided

5.A set of jump cap. Jump hat off. Can separate the power supply

6.Only one way of high level can be triggered

Package Including:

1*Relay Module 

 

Arduino test code:


int BASE = 2; / / first a relay connected to I / O pins
int NUM = 4; / / the total number of relay
void setup ()
{
for (int i = BASE; i <BASE + NUM; i + +)
{
pinMode (i, OUTPUT); / / set the digital I / O pin as an output
}
}
void loop ()
{
for (int i = BASE; i <BASE + NUM; i + +)
{
digitalWrite (i, LOW); / / set the digital I / O pin output is "low", that is gradually closed relay
delay (200); / / delay
}
for (int i = BASE; i <BASE + NUM; i + +)
{
digitalWrite (i, HIGH); / / set the digital I / O pin output is "low", that gradually open relay
delay (200); / / delay
}
}
