Surely, there must be more ways for a computer to interact with its environment

Input and output (think, write, pair, share)

Think about the ways that mobile computers (e.g. mobile phones, tablets, smartwatches) interact with the user and their environment.

Use your worksheet to write down how they receive input and provide output.

In the previous units, you...

Used a text-based programming language (Python) to create programs that involved:

●Variables, operators, expressions

●Sequence, selection, iteration

●Lists, strings

print("Hello Python!")

In this unit, you will...

Use a text-based programming language (MicroPython) to create programs that:

●Run on the micro:bit

●Interact with the physical world

display.show("Hello world!")

In this lesson, you will:

●Explore the micro:bit’s hardware components, to develop an awareness of its capabilities

●Create your first programs for the micro:bit, and go through the process of flashing and running them

Know your tools:


What is a microbit?

MICROBIT:

The micro:bit is a tiny computer.

It’s a microprocessor that can execute a single program at a time.

You can write programs for the micro:bit on your computer and then transfer them to the micro:bit to be executed.

• Knowing our tool,

• front side

  
  
  

1. Buttons: input

   Capture user input to make things happen

2. LED display: output

   Show pictures, words, and numbers

3. Light sensor: input

   Measure how much light is falling on the micro:bit

4. GPIO pins: input and output

   Connect headphones, sense touch, and add other electronics

Back side,

5.Temperature sensor:
inputMeasure how warm the environment is
6.Compass: input

Find magnetic north or measure the strength of magnetic fields
7.Accelerometer: input

Detect gestures and measure movement in 3 dimensions
8.Radio: communication i/o

Communicate with micro:bits and other devices
