Re: Speed Sensor for Ball Shooter

As with the previous device, this should work. Just remember that the accuracy depends on a lot of variables, sense clicks/rotation, linearity in the ADC, power supply, etc. You could increase the number of sense points on the wheel (2 per rotation or 4/rot, etc.) but you still are subject to the accuracy of the ADC on the input of the RC and it's conversion to bits. Will the number in this conversion give you enough accuracy?
