we have a project to pass, it is a design project which entitled "AUTOMATED LIGHTNING SYSTEM with ONLINE ACCESS" instead of using mechanical relay for this project we will use an optocoupler to drive 220v AC controller and 5v DC driver through USB port and arduino. we will just make a building which is a miniature, our problem is the optocoupler that we will be used for this can yo suggest what we can use?
