I was wondering if anyone would be able to help me. I have recently been given the task of making a circuit design when I have no electrical experience, so I have been stumbling my way through and hit a roadblock. I am trying to make a circuit in which there is a switch which will be turned on at all times, until an arduino gives an output and turns it off. The circuit needs to be like this, as it will be in the on state for most of its life, but I will have certain times when I need to turn the switch off for a short period of time. Any ideas?
