Presenter's guideline - WS2 : Conveyor & Sensor Integration

Step 8: Add IR Logic to Stop the Conveyor

Action:

• Add a While loop that runs the conveyor until the object is detected.
  
  

• Condition: While DI5 is HIGH → keep conveyor on.
  
  

• After loop: Stop conveyor.

Speaker notes:

“Now we add the logic to stop the conveyor when the IR sensor detects the object. Remember: DI5 is HIGH when no object is detected, and LOW when an object is detected.”

“So I’ll add a While DI5 is HIGH loop — this means the conveyor will keep running while no object is detected. As soon as DI5 changes to LOW, the loop ends and I immediately stop the conveyor.”

“Let’s run it and see — the object should stop just on the IR sensor.”
