Hello, I am working on a Energy saving escalator and I really need help with the code. There are 2 Line follower, 1 at the start and 2nd on the end. When an object passes the linefollower1 , the motor starts and the object is added in the code as a person 1 and when the object passes the linefollower2 the person is removed from the code and the motor stops. For example: 5 people crossed the linefollwer1, which starts the motor and those 5 people are added in the code as 5. After they pass the linefollower2 they are removed from the code and the motor doesn’t stop unless all the 5 people are out of the linefollower2 which is the exit. I really appreciate the help!
What software are you using to program and are you using Cortex or V5?
Can you post the code you have been working on?
You could probably do a simple count system where if something passes the first line sensor the count becomes count + 1 and if count is > 1, the escalator motor spins. Else motor is off. If the second line sensor is crossed count becomes count - 1.
I am using Cortex and I am pretty much new to programming. Just looking for someone to help me figure out the code for counting system.
I just wrote this and this one does start the motor, but doesn’t stop afterwards:
#pragma config(Sensor, in1, exit, sensorLineFollower)
#pragma config(Sensor, in2, enter, sensorLineFollower)
#pragma config(Motor, port2, mainmotor, tmotorVex393_MC29, openLoop)
//!!Code automatically generated by ‘ROBOTC’ configuration wizard !!//
int countValue = 0;
int enterValue;
int exitValue;
task main()
{
while (1==1)
{
if(SensorValue(enter)<=2500)
{
enterValue=SensorValue(enter);
countValue = enterValue + 1;
{
while(countValue > 1)
{
startMotor(mainmotor, -15);
{
if(SensorValue(exit)<=2500)
{
exitValue=SensorValue(exit);
countValue = exitValue - 1;
{
while(countValue < 1)
{
stopMotor(mainmotor);
{
}
}
}
}
}
}
}
}
}
