Single Channel 220V-10A 5V Relay

----

A relay is an electrically operated switch. 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.

Description

5V Relay is needed for having your Arduino control higher-power devices like lights, motors, pumps, in addition to doors locks, and much more is one of the most interesting and useful applications you may get involved with. But it can be a little difficult and possibly dangerous when power line voltages are being controlled. Furthermore, there are significant differences in controlling AC power compared to DC.

5V Relay Specifications

  • 5V Single Channel Relay interface board, and needs 15-20mA Driver Current
  • Also, equipped with high-current relay, AC250V 10A ; DC30V 10A
  • Standard interface that you can control directly by microcontroller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic)
  • Indication LED’s for Relay output status

Required Hardware Devices

  • Arduino controller × 1
  • USB data cable × 1
  • 1 relay module × 1

Connecting

  • Arduino digital pin 10 –> module pin IN
  • Arduino GND –> module pin –
  • Arduino +5V –> module pin +

Code

//KY019 5V relay module
int relay = 10; // relay turns trigger signal - active high;
void setup ()
{
  pinMode (relay, OUTPUT); // Define port attribute is output;
}
void loop ()
{
  digitalWrite (relay, HIGH); // relay conduction;
  delay (1000);
  digitalWrite (relay, LOW); // relay switch is turned off;
  delay (1000);
}
