I am trying to controll some lights connected to a power strip(about 500w total) with my arduino, but havn't really worked alot with high power before so wanted to make sure i wasn't about to do anything stupid that will ruin my arduino or anything even worse.
As im new to this i tried with a 6v dc adapter as it felt abit safer,
I have connected it the following way and it works as it supposed to.
i can switch computer fans or what ever i want on and off.
But if i now want like to controll more power can i just skip the 6v dc adapter and connect it straight to the wall and on the other end of the relay connect a power strip and then controll all my lights?
I have no need of controlling them one by one, i just need to turn on/off the entire power strip.
Thanks for the tip, i will have to look in to those, but is it really that dangerous to work with main voltage, i fully understand it can be and you can die if your doing something stupid, but is it really so dangerous that it shouldn't be done without powerswitchtail?
