Hi, basically I want to use a relay to turn on a lamp with my arduino uno r3, but I'm not sure what relay to use. The lamp uses 24 watts so I know I need to use a relay that's capable of twice the power for safety. Which one would you recommend? Thanks.
One that is rated for about 2A and whatever voltage your line is.
So my line is 240v so what I look for a relay with 2a and 240v?
