Re: Sensor for finding out angle?
Just brainstorming a few ideas. If you don't like the idea of potentiometer, you
Could use a magnet and a 2 axis magnetometer (actually, you might be able to get away with just a single axis if you set it up right).
Could also use a 2 axis accelerometer (mount it to your shooter and measure which way gravity is pointing).
Could also use a rotary encoder.
could probably use your webcam if you set it up properly.
Or you could use a strain gauge if you attach a spring to your shooter.
But most people have reasonable success with a potentiometer.
