PLTW POE - Going the Distance Flashcard

Front

What is the main characteristic of an open loop control system?

Back

Runs blindly through the program

Front

Closed loop control system works based on feedback, where a sensor measures the output and adjusts the input accordingly.

Back

It uses feedback for adjustments.

Front

What is the difference between a VEX V5 digital and analog sensor?

Back

Digital sensors output binary (0 and 1) signals, whereas analog sensors output continuous signals.

Front

Which type of sensor is only an analog sensor?

Back

Potentiometer.

Front

What is the effect called when a sensor is pressed or released too quickly, causing the VEX V5 brain to register multiple presses?

Back

Bouncing

Front

Explain how using a brief wait can help in reducing the bouncing effect in sensors.

Back

It allows time for the sensor to stabilize, reducing false triggers caused by signal fluctuations.

Front

Which of the following is a caution to consider when using a limit switch? The lever is very strong and durable. The lever can be fragile and may need to debounce. The sensor requires a large amount of force to trigger. The lever should be placed in a tangled area.

Back

The lever can be fragile and may need to debounce.

Front

How does a Bumper Switch work?

Back

It detects physical contact through mechanical movement.

Front

What does the V5 Distance Sensor use to measure distance?

Back

Laser light

Front

The V5 Distance Sensor can detect an object's size as small, medium, or large. True or False?

Back

True
