Model Artificial Pancreas Science Project

Dr. Ben Finio introduces a model artificial pancreas project using Arduino to simulate a feedback control system. The project involves mixing distilled and tap water to represent blood and insulin, respectively. The video explains diabetes, feedback control, and the design of a model system. It demonstrates how to use a circuit to measure voltage as a proxy for blood glucose levels and shows how an automatic feedback system can be created using a pump controlled by Arduino.

What is the main goal of the model artificial pancreas project?

• To measure blood glucose levels directly

• To design a feedback control system using Arduino

• To create a new type of insulin

• To build a real artificial pancreas

How does the body naturally regulate blood glucose levels?

• By releasing insulin

• By producing more blood cells

• By increasing heart rate

• By releasing adrenaline

What is the role of a continuous glucose monitor in diabetes management?

• To replace the pancreas

• To constantly monitor blood glucose levels

• To inject insulin automatically

• To measure blood pressure

In the model project, what does distilled water represent?

• Insulin

• Blood

• Carbohydrates

• Glucose

Why is a voltage divider circuit used in the project?

• To convert resistance to voltage

• To measure temperature

• To increase water conductivity

• To decrease voltage fluctuations

What does a higher voltage reading indicate in the model?

• Higher blood glucose level

• Lower blood glucose level

• More insulin

• Less insulin

What is a key factor affecting the conductivity sensor's reading?

• The color of the water

• The temperature of the room

• The exposed surface area of aluminum foil

• The type of Arduino used

What happens when tap water is added to the model system?

• Voltage remains constant

• Voltage decreases

• Voltage fluctuates randomly

• Voltage increases

Why is mixing important in the model demonstration?

• To change the color of the water

• To increase the speed of the pump

• To decrease the voltage reading

• To ensure even distribution of tap water

What is the purpose of the Arduino in the model project?

• To change the water's color

• To heat the water

• To control the pump based on voltage readings

• To measure blood glucose levels
