How to Test a Prototype of Your Electronic Circuit
Hello! This is Ross on behalf of expertvillage.com. I am going to prove that the circuit will work with a 9 volt battery before I take and mount it all. So, go ahead turn the power off, there we go and the 9 volt battery I am going to connect up now the positive on this, that is the negative one that means that’s the positive and put a clip there and I will disconnect this and I will touch this connection here and the light comes on with a 9 volt battery. Alright, that was good. What you want? I would want that to be sure to work.
