Circuit
If you want to stop electricity from moving through a circuit, you can press this component to "break" the path. You use them on walls to turn lights on and off!
What is a switch?
If you want your Arduino to do something over and over again forever (like blink a light), you put your code inside this function.
What is the loop function?
What is the 4-letter "C" word that means writing these instructions to the computer.
What is code?
This tiny, glowing bulb lights up your projects. Just make sure you plug its long leg (the positive side) into the right spot!
What is an LED?
These metal holes on the side of the Arduino board are where you plug in your wires. They have numbers on them so you can tell the code where to send electricity!
What are pins?
In Wokwi, you can add this noisy component to your virtual circuit to play simple video game music or make beep-beep sounds.
What is a buzzer? (or speaker)
This component acts like a "traffic cop" for electricity. It slows down the electric current so it doesn't rush in and pop your LED.
What is a resistor?
These plastic-covered conductors are what you use to connect your Arduino to your LEDs.
What are wires?
In Wokwi, you can run your code virtually on the screen without needing a real USB cable. To do this, you click the button with this green, triangle-shaped icon.
What is the Play button? (or Start Simulation)
This shiny, silver material is melted with a hot "iron" pen to permanently glue wires and parts together on a circuit board.
What is solder?
This is the name of the special computer program where you type your code and send it to your Arduino board.
What is the Arduino IDE?
This common computer accessory, which shares its name with a tiny squeaking rodent, is what you use to drag-and-drop parts around the Wokwi screen.
What is a mouse?
This is the name of the plastic board full of tiny holes that you use to plug in wires and test your circuits without having to glue or solder anything.
What is a breadboard?
If you make a typo in your code, the computer will give you this kind of message to tell you something is wrong.
What is an error?
The "brain" board of your project is named after a town in this European country, where its creators went to school.
What is Italy?
