Speed Sensor for Ball Shooter
Does anyone have and idea for a speed sensor for the ball shooting wheels, I don't really want to use encoders, I had an idea of using a frequency to voltage IC and connecting it to the analog port of the R/c as I don't need direction or exact positioning and would rather not go into interrupts. The wheel would have an optical sensor mounted with a disk on the shaft or something similar, however all the frequency to voltage chips I saw wanted about 15 volts in and like 100Hz. The frequency is doable, but theres no way I want 12v battery voltage going into the r/c if something goes wrong. So anyone have an idea?
my priorities Very little coding cheap commonly available easy to interface not necessarily in that order. |
