Arduino Radio Controlled Boat Quiz

What is one of the primary benefits of using onboard cameras in radio-controlled vehicles?

• They enable recording in hard-to-reach or dangerous areas.

• They allow for better navigation in open waters.

• They increase the vehicle's battery life.

• They improve the vehicle's speed.

What is the purpose of the double hull design in the boat?

• To increase the boat's speed.

• To provide extra waterproofing and protection for electronics.

• To make the boat more buoyant.

• To reduce the boat's weight.

What component acts as the 'brains' of the boat's operation?

• The lithium battery

• The Arduino

• The H Bridge

• The propellers

Why is it important to use brushed DC motors for this project?

• They are cheaper than brushless motors.

• They require less maintenance.

• They are easier to control with the Arduino using an H Bridge.

• They are more powerful than brushless motors.

What safety precaution should be taken when working with lithium batteries?

• Store them in a metal container.

• Always keep them fully charged.

• Avoid short circuits and keep the workspace tidy.

• Use them only in dry conditions.

What is the purpose of using silicone sealant in the assembly process?

• To improve the boat's aesthetics.

• To make the boat more buoyant.

• To waterproof the holes drilled for wires.

• To enhance the boat's speed.

Why is it recommended to test the boat in a bathtub before larger bodies of water?

• To measure the boat's speed.

• To practice steering the boat.

• To check for leaks and ensure the electronics are safe.

• To ensure the boat floats.

What should you do if the motors spin in the wrong direction during testing?

• Increase the battery voltage.

• Swap the wires or adjust the Arduino code.

• Replace the motors.

• Reposition the propellers.

What is the main reason for using a higher-end food storage container for the boat?

• To make the boat look more professional.

• To ensure it is airtight and leak-proof.

• To reduce the overall cost of the project.

• To increase the boat's speed.

What is the final step before testing the boat in a real-world environment?

• Calibrating the remote control.

• Adding extra weight for stability.

• Ensuring the motors are working correctly.

• Painting the boat.
