My project is a mouse that is searching for cheese; it stops to eat cheese it finds. While its searching it avoids objects.
The part of the program that makes the mouse search and avoid objects is working, but the part that uses a light sensor to find the "cheese" (blank piece of paper) is not working properly.


#pragma config(Sensor, S1, lightSensor, sensorLightActive)
#pragma config(Sensor, S2, sonarSensor, sensorSONAR)
//*!!Code automatically generated by 'ROBOTC' configuration wizard !!*//

task main()

{
while(true)
{
while(SensorValue[sonarSensor] > 20)
{

motor[motorA] = 75;
motor[motorB] = 75;

//while (SensorValue[lightSensor] > 18)
//
//{
//motor[motorA] = 0;
//motor[motorB] = 0;
//wait1Msec(3000);
//}

}

motor [motorA]= -50;
motor [motorB]= -50;
wait1Msec(500);
motor [motorA]= -50;
motor [motorB]= 0;
wait1Msec(600);

}
}

Try it like that:

//*!!Sensor, S1, lightSensor, sensorLightActive, , !!*//
//*!!Sensor, S4, sonarSensor, sensorSONAR, , !!*//

const tSensors lightSensor = (tSensors) S1; //sensorLightActive //*!!!!*//
const tSensors sonarSensor = (tSensors) S4; //sensorSONAR //*!!!!*//


task main()

{
while(true)
{
while(SensorValue[sonarSensor] > 20)
{
motor[motorA] = 75;
motor[motorB] = 75;
}

while (SensorValue[lightSensor] > 30)
{
motor[motorA] = 0;
motor[motorB] = 0;
wait1Msec(3000);
}

}

motor [motorA]= -50;
motor [motorB]= -50;
wait1Msec(500);
motor [motorA]= -50;
motor [motorB]= 0;
wait1Msec(600);

}
