PWM pins
Analog pins
Power supply pins
What is the primary use of a breadboard?
To amplify electrical signals
To permanently attach components in a circuit
To prototype and test electronic circuits without soldering
To store electrical energy
Why is it important to wear safety goggles when working with electronics?
To improve vision
To protect eyes from flying objects or sparks
To make soldering easier
To follow school rules
What should you do if you are using a power tool and have long hair?
Leave it loose
Cover it with a plastic bag
Tie it back securely
Wear a cap
Why is it important to keep your workspace clean?
To avoid distractions
To reduce the risk of accidents
To make it look presentable
To have more space for tools
What is a key reason to avoid working with Arduino electronics when sleepy?
Lack of sleep may lead to errors and accidents
Sleepy people cannot understand circuits
Electronics do not function properly at night
Soldering is more difficult when tired
Why should you only use tools for their intended purpose?
To avoid damaging the tool and injuring yourself
Because teachers require it
Because the tools will not work otherwise
So that they last longer
What is the main reason for being aware of your surroundings in a workshop?
To prevent distractions while working
To ensure safety for yourself and others
To keep the area clean
To show respect for the workspace
Which of the following is NOT a recommended safety practice?
Wearing protective clothing when necessary
Using a screwdriver as a pry bar
Keeping work areas organized
Following tool-specific safety guidelines
What should you do before using a new tool?
Ask an experienced person for help or watch tutorials
Experiment with it without learning first
Assume it works like every other tool
Use it without any precautions
What should you do if you notice an unsafe condition in the workspace?
Ignore it and continue working
Report it and correct it if possible
Move to another area and avoid it
Ask a friend to check it later
Why is it important to follow safety rules when working with Arduino projects?
To avoid accidents and injuries
To follow school regulations
To ensure the project works correctly
To avoid breaking components
