7th Grade ICT Conceptual Assessment topic A.

Through a flowchart,

• I can program a computer.

• I can organize a program graphically to analyze step by step what it does and understand it better.

• I can make a circuit in Tinkercad.

• I can program in mBlock.

What is the main characteristic of the Arduino board's Power pins? Select the correct sentence:

• Power pins detect different signal variations.

• Power pins have only two states: on or off.

• Power pins power electronic devices that connect to the positive terminal (five or three volts) and the negative ground terminal (GND).

Select the correct sentence below about the Arduino board's PWM pins.

• These are the same power pins that power devices with connections to five volts, three volts, or GND.

• These are the same analog input pins that detect signals with different variations.

• These are the same digital pins that only provide on and off signals.

• PWM pins can function as digital pins (two states, on and off) or as analog output pins (with variable signals) and are marked with a small waveform next to their number.

If I want to analyze sensor data using TinkerCad with an Arduino board, which set of blocks should I use to view the data it provides? Select the correct answer below:

•

If I want to connect the shorter leg of an LED to the Arduino board, I must connect it to:

(a)  

Which Arduino pins should I use if I want to gradually change the light intensity?

• The digital pins of the Arduino board.

• The analog pins of the Arduino board.

• Using only the power pins, I can gradually change the intensity of an LED.

What is the main characteristic of the Arduino board's Digital pins? Select the correct sentence:
