What does the 'void setup()' function do in Arduino programming?
It is used to control the speed of the Arduino board
It is used to print output to the serial monitor
It is used to define the size of the Arduino board
It is used to initialize the Arduino board and run only once when the board is powered on or reset.
What does the 'delay()' function do in Arduino programming?
Stops the program completely
Pauses the program for a specified number of milliseconds
Resets the program to its initial state
Skips the next line of code
How can you change the duration of each traffic light phase in the Arduino code?
Add more sensors to the traffic light
Modify the delay time in the Arduino code for each phase
Increase the voltage to the traffic light
Change the color of the traffic light
What is the role of a breadboard in circuit design?
To act as a power source for the circuit
To provide a stable foundation for the circuit
To create temporary circuits for testing and prototyping without soldering.
To heat up the components for better conductivity
What is the difference between series and parallel circuits?
In series circuits, the current has only one path to follow, while in parallel circuits, the current has multiple paths to follow.
In series circuits, the current has multiple paths to follow, while in parallel circuits, the current has only one path to follow.
In series circuits, the voltage remains the same across all components, while in parallel circuits, the voltage changes across components.
In series circuits, the resistance adds up, while in parallel circuits, the resistance remains the same.
What is the purpose of using a push button in the traffic light project?
To activate the sprinkler system
To play music
To allow pedestrians to request a crossing
To change the color of the traffic light
What is the purpose of using a 'for' loop in Arduino programming?
To repeat a block of code a specified number of times
To stop the program completely
To skip the next line of code
To reset the program to its initial state
What is the role of a resistor in an LED circuit?
To increase the flow of current and make the LED brighter
To limit the flow of current and prevent damage to the LED
To change the color of the LED
To control the temperature of the LED
What is the formula for calculating resistance in an electrical circuit?
R = V / I
R = I / V
R = V * I
R = V - I
Which Arduino pins are commonly used to connect the LEDs representing the traffic light colors?
Analog pins
5V and GND pins
Digital pins
PWM pins
What is the purpose of using Tinkercad in the development of a traffic light project?
Tinkercad adds visual effects to the traffic light
It allows for simulation and testing of the project
Tinkercad provides background music for the project
It helps with soldering the components
For a traffic light project, if the voltage across a resistor is 5 volts and the current flowing through it is 0.02 amperes, how would you calculate the resistance using Ohm's Law?
resistance = voltage / current
resistance = current / voltage
resistance = voltage * current
In addition to Morse Code and Traffic Lights, briefly describe 2 OTHER Arduino projects you can create using mainly LEDs (think in real solutions).
