Magnetic switch to USB?
Hi, 1st post hope you can help! I'm trying to find a way of getting analog data (from an exercise bike) and store it onto a computer in a text file so I can manipulate it and work out averages etc.
I thought of having a magnetic switch on the pedal so that everytime the pedal rotates I can store the time thus giving me the speed.
Does anyone know if such a cable already exists or if not how to go about creating one?
Also if anyone has a better way of getting the data I'd love to hear from you.
