Ok so i am currently studying A level technology and i’m doing coursework. My product is a kind of conveyor belt sorter that activates when 10 components (the components i am using are just simple switches) pass a certain point. The output should be a motor that moves to a specific position, then back to its original one. I actually already have the circuit i will be using, but for my project i need around 5 (i already have 2) circuits to choose from. Obviously 4 of them will not be chosen, so i need circuit ideas for these 4. They should be relevant to my topic, but lack things that need to be in the final circuit (so they can be denied). I am really stuck here, can anyone help?
