    Output logic source and sink

    Hi all, Im working to design a circuit that can sink after a load is apply, but when there's no load also be able to output logic levels 5v/0v. The max that a load could be is 12V and not not more than 100ma, therefore I decided to use octocapulers to make some output logic. In my attach image...

    I'm currently designing a Smart Helmet that's planned to have Sensors hooked up and sent through a PCB (with circuit protection and power components). So far how I've gotten is that since this project is homemade for a first time concept prototype coming to life, I have a USB splitter (up to 8...
