I am looking for a new way to control a motor I do not know much about sensors of these types but i am looking for something that uses reflective light. also, I had a question on how they tend to work, I need something that can output a positive voltage a 5V, if they normally can do this? The ones that do not have transistors but internal regulators can operate differently please let me know what it is and where I can get it. my final request is that it be fairly compact but it can be long and fairly cylindrical if need be. Thanks.
