How to build an Arduino controlled 120VAC relay with an indicator LED?
I am working on a project where I am going to collect grey water under my sink and use an Arduino to run two relays. One relay will turn on a pump that will move the water in the reservoir to the tank of the toilet. The other relay will turn a valve connected to the municipal water supply of finish filling the tank if necessary. The float valve in the toilet will make sure the water does not overflow.
Does anyone see any problems with the circuit I have built? I am new to electronics and cautious as I bridge the gap between my 5v world and the 120v world beyond.
Thanks for any help you can provide.
