keyestudio 8-channel 5V Relay Module

Introduction

Arduino Relay Shield employs high quality relay with eight channels input and eight channels output. It can be connected to 250V/10A AC element or 24V/10A DC element to the maximum, therefore, it can be used to control lights, motors,etc.
The modularized design makes it easy to connect to Arduino expansion board. The output state of the relay is shown by a luminous diode for the convenience of actual application.

Specification

• Control signal: TTL voltage
• Active at HIGH level

iii) Ground (GND)

Connection Diagram

Sample Code

int BASE = 2 ;  // I/O pin connected by the first relay
int NUM = 8;   //total number of all relays
void setup()
{
   for (int i = BASE; i < BASE + NUM; i ++) 
   {
     pinMode(i, OUTPUT);   //set digital I/O pin as output
   }
}

void loop()
{
   for (int i = BASE; i < BASE + NUM; i ++) 
   {
     digitalWrite(i, LOW);    //set digital I/O pin as ‘low’, i.e. turning off the relay gradually    
 delay(200);        //delay
   }
   for (int i = BASE; i < BASE + NUM; i ++) 
   {
     digitalWrite(i, HIGH);    // set digital I/O pin as ‘low’， i.e. turning on the relay gradually    
 delay(200);        //delay
   }  
}
