​This section is going to very short , it's just going to explain the content of the project box and then we will get back to the construction of the laser setup.The laser project box so far is pretty simple it has the arduino,screw shield and the relay shield which are all stacked together, then their is the wire relay boards they are not actual RELAYS I just call them that because the help organize the wires.Simply put they help keep the stress of the laser circuit and the power system from actually interfering with the arduino section.Is this the best way of doing it? I dont know but it is simple.So we shall see if it actually works .Ohh I almost forgot the 9v battery powers the relay (I'll go into this in farther detail when I get there).And yes I know the photo sucks sorry It was getting late.
