Hello,
I want to control the 220V lamp by using arduino uno r3 and relay. I want to connect the relay to a digital pin. When the value is 1 then the lamp mode is on. 0 off.
Is the relay the following link for this purpose?

Features :
- the item is a 5v 1-channel relay interface board,It can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on.
- 1-Channel Relay interface board,
- Each one needs 15-20mA Driver Current
- Equiped with high-current relay : DC30V 10A AC250V 10A
- Standard interface that can be controlled directly by microcontroller


Thank you

Yes, this one is okay for you.

As far as I know this relay has 5 pins. Two for the coil, and three for the switching contacts. That is why the header has three contacts. You just need two of them for switchting something on.
