We are trying to use a raspberry pi to record the current going through a dc circuit. The circuit we are trying to measure the current in is powered by a car battery. We have no idea how to record the current and input it into the pi. Plus the entire circuit has to powered of one 9v battery or similar it has to fit into the greenpower f24 regulations. It has to be a pi an Arduino or similar is not an option plus we need the results in a spreadsheet. Thanks in advance.
