How can you get the exact distance on a sonar? Thanks.:mad:
You probably should tell us which computer language you’re using. RobotC? EasyC? or what?
For RobotC:
In Motors and Sensors setup wizard, you pick what units of measurement you want your values to read in (I believe the options are in, cm, or mm).
Possible commands/uses:
//this returns (I believe) an integer value from the sensor
//note that it is not an actual command, it is just a number.
SensorValue[ultrasonicSensorName]
//to actually use it, you could do things like
//assign it to a variable:
int distanceFromSensor = 0; //declare and initialize
distanceFromSensor = SensorValue[ultrasonicSensorName]; //assign
the current value of the sensor to distanceFromSensor
//how about a logical test?
if(SensorValue[ultrasonicSensorName] < 5)
{
//do something if the sensor value goes below 5 (whatever
// units you selected in the wizard)
}
Hope this helps you. If not, anyone else can see it and maybe be helped by it.
