100

This instruction pauses the program execution for one second.

What does "delay(1000);" do?

100

This kind of signal is defined over every time instant.

What is an analog signal?

100

Is the electrons pass though a conductor.

What is electricity?

100

In electronics, it is a system that converts an analog signal, such as a sound picked up by a microphone or light entering a digital camera, into a digital signal.

What is an analog-to-digital converter (ADC)?

100

They are the names you give to computer memory locations which are used to store values in a computer program.

What are variables?

200

This function sets the LED output port with a 5 V value.

What does "digitalWrite(LED, HIGH);" do?

200

This kind of signal is defined on only certain instants of time.

What is a digital signal?

200

It is composed of individual electronic components, such as resistors, switches, diodes, etc., connected by conductive wires through which electric current can flow.

What is an electronic circuit?

200

In electronics, it is a system that converts a digital signal into an analog signal.

What is a digital-to-analog converter (DAC)?

200

It is a combination of computer hardware and software designed for a specific function.

What is an embedded system?

300

This function reads the voltage from port 34 and returns the corresponding value between 0 and 4095.

What does "analogRead(34);" do?

300

It is an unwanted disturbance in an electrical signal.

What is the noise?

300

It is a measure of the opposition to the flow of electric current.

What is the electrical resistance?

300

Contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit.

What is a microprocessor?

300

It is the automatic system that performs the measurement and wireless transmission of data from remote sources.

What is a telemetry system?

400

This instruction sends through the serial communication output port the message "Hello world!".

What does "Serial.println("LED is on");" do?

400

A computer is a programmable device that stores, retrieves, and processes data.

What is a computer?

400

It is the rate at which electrical energy is transferred by an electric circuit.

What is electric power?

400

It is a form of a volatile computer memory that can be read and changed in any order, typically used to store working data and machine code.

What is a Random-access memory (RAM)?

400

It refers to any information processing system with hardware and software components that perform real-time application functions and can respond to events within predictable and specific time constraints.

What is a real-time system?

500

This directive subsitutes every LED word as the number 23.

What does the line "#define LED 23" do?

500

It is the smallest possible change that a sensor can perceive. 

What is a sensor resolution?

500

It states that the current through a conductor between two points is directly proportional to the voltage across the two points.

What is the Ohm's law?

500

It is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave, a square wave or a triangle wave.

What is an oscillator?
500

It is a modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal.

What is Pulse width modulation (PWM)?
