What is a circuit?
A circuit is a type of geometric shape used in electronics.
A circuit is a pathway through which an electric current can flow.
A circuit is a pathway that does not allow electric current to flow.
A circuit is a large microcontroller
Why are breadboards used in electronics?
To allow the user to practice their soldering technique when adding components to a circuit
So a user can eat a sandwich on it while making electronic circuits
To make sure LEDs work in our circuits
What does this symbol represent in a circuit?

Ultrasonic Sensor
What does this symbol represent in a circuit?
Resistor
LED
Battery
Why would this circuit not work?
There need to be a resistor between the power rail and the LED to reduce the amount of electrical current flowing to it
The battery needs to be replaced with an Arduino board
The LED is a broken component and should be replaced
In Tinkercad block code, what does the word HIGH do?
Turn something on
It indicates a full battery level
Turn something off
In a circuit, what does a potentiometer do?
Changes the amount of electricity in a circuit by turning a dial
It changes the colour of the circuit components
It plays sounds in the circuit
In Tinkercad and Arduino, what's the purpose of the Serial Monitor?
What is the difference between analog and digital pins on an Arduino board?
Analog pins can read analog voltage values (between 0 and 1023), while digital pins can only read digital values (0 or 1).
What does a piezo buzzer do in a circuit?
It generates sound waves by vibrating a membrane
It measures temperature in the circuit and buzzes if it reaches a threshold
With a piezo buzzer, faster vibrations make which sort of sound?
Low pitch
High pitch
How does an ultrasonic sensor work?
An ultrasonic sensor works by analysing temperature changes in the environment to determine distance.
What does a photoresistor do in a circuit?
