What kind of switching circuit do I use with Arduino Answered
I have a 3V battery pack connecting to a single circuit. I want to replicate this circuit 10+ times using the same battery pack as a source. I need to apply some sort of 'switch' to control the follow of current amongst the circuits, hence turn on/off various circuits as needed. For instance, I have 10+ servo motor circuits. I want to connect the single battery to each circuit and control which circuit gets the current from the battery. I have an arduino but I don't know how to interface it with what I am trying to achieve. Any suggestions?
