Value of degree to calculate range?

[paulcd2000]

i dunno where you learned that you need radians... i use degrees. if you look in tracking.H, you'll see the upper and lower servo limits are (i think) 160 and 94. It also says that that's approximately +25 deg and -25 deg. so degrees per servo step is 25/33. then, you need to find the number of servo steps either up or down. i did something like:

unsigned float Find_Distance(void)
{
     double angle;
     double range;
     angle = (TILT_SERVO-127)*.757575;
     range = HEIGHT_DIFF /*that's 116- camera height*/ /atan(angle);
     return(range)
}

make sure to double check, but this should do it...
