blog 500

In this blog, we will embark on a thrilling journey through the realms of Arduino, Raspberry Pi, and Microbit, demystify their capabilities, and illuminate the ideal terrain for each platform.

What is Arduino?

Arduino

 

The microcontroller board Arduino is a master of hands-on interactivity; it can receive data from sensors, operate motors and LEDs, and react to its surroundings. Imagine your Arduino code controlling things like blinking lights, dancing robots, and environmental sensors. It's ideal for both novices and experienced enthusiasts due to its robustness and simplicity.

 

Who Invented Arduino?

A team of researchers from the Interaction Design Institute Ivrea in Italy developed the Arduino platform. In particular, the institute's teacher Massimo Banzi was instrumental in its growth. He needed a low-cost microcontroller platform on which his students could learn about custom programming and electronics. As a result, the Arduino project was started in 2005 to give both experts and beginners a simple way to construct gadgets that use sensors and actuators to interact with their surroundings. A tavern in Ivrea, Italy, where some of the project's founders used to get together, is where the name "Arduino" originates. It's interesting to note that Arduin of Ivrea, who ruled Italy as King from 1002 to 1014 and served as the margrave of the March of Ivrea, inspired the name of the bar.

 

What’s Raspberry Pi?

Raspberry Pi

 

Transparent as a credit card, the Raspberry Pi is a tiny computer. Beyond just blinking an LED, the Raspberry Pi's entire Linux operating system (imagine a little Ubuntu!) gives up a world of possibilities. There are countless ways to use AI to make robots, search the web, stream media, host a website, and code in languages like Python and Java.

 

What’s Microbit?

Microbit

 

The Microbit is a tiny computer that's meant to expose people to electronics and coding, particularly kids. It's an adaptable tool that can be applied to a range of projects, from straightforward animations and games to intricate robots and weather stations.

 

When was Microbit Created?

The BBC and its partners invented the microbit, also referred to as the BBC microbit. As a component of the Make It Digital campaign, it was initially introduced in 2015. The goal of this endeavor was to pay tribute to the BBC's computing heritage, which began with the BBC Microcomputer of the 1980s12. With its pocket-sized computer, the microbit was created to encourage children's creativity and learning while allowing them to experiment with electronics, programming, and physical computing. Millions of microbots have been distributed worldwide since its launch, enabling young students and enthusiasts to interact with technology in novel and engaging ways.

 

How Arduino Works?

The core of Arduino is an ATMEL AVR microcontroller.

Here’s how it works:

  • Programming: The Arduino IDE (Integrated Development Environment) is used to write your code.
  • Uploading Code: The Arduino board is instantly updated with the code.
  • Input and Output Devices: Connect input devices, such as buttons and sensors, and output devices, such as LEDs and motors.
  • Execution: Until it is switched off, the Arduino board executes the uploaded code each time it turns on.

 

How Arduino is Programmed?

  1. Writing Code:
    • Using the Arduino programming language, you design your own Arduino sketches or programs.
    • The language is designed especially for Arduino development and is based on C++.
    • To specify the behavior of your Arduino board, such as receiving inputs (like sensor data) and managing outputs (like LEDs, and motors), you write code.
  2. Arduino Software (IDE):
    • A desktop program called the Arduino IDE (Integrated Development Environment) is connected to the Arduino board.
    • It functions on Linux, Windows, and Mac.
    • It is available for download on the official Arduino website.
  3. Creating a Sketch:
    • You open the IDE and select File > New to start a new drawing.
    • You write your code in the text editor, which is saved with the file extension .ino.
  4. Uploading Code:
    • Utilize USB to connect your Arduino board to your PC.
    • In the IDE, go to Tools > Board and Tools > Port and choose the appropriate board type and port.
    • To upload your code to the Arduino board, click the Upload button.
    • The uploaded code is run by the board's microcontroller.
  5. Debugging and Iterating:
    • The IDE gives you helpful notifications if there are mistakes in your code.
    • Until your sketch performs as intended, you can refine, iterate, and improve it.
  6. Libraries and Examples:
    • For usage in your projects, the Arduino community has produced a large number of libraries (pre-written code).
    • You can study and experiment with various functionalities by using the built-in examples in the IDE.
  7. Hardware Interaction:
    • The hardware (actuators, sensors, etc.) attached to the board communicates with your Arduino sketch.
    • This allows you to move servos, read sensor values, and control LEDs.

 

How Raspberry Pi Works?

  1. Turn on the Raspberry Pi: The bootloader software on the SD card is run by the CPU as soon as the device is powered on.
  2. Operating System Load: After that, the operating system is loaded into the RAM by the bootloader from the SD card.
  3. Desktop Interface: The operating system presents a desktop setting from which you may run programs, handle files, and configure the Raspberry Pi.
  4. Connecting Peripherals: To connect a keyboard, mouse, monitor, and other devices, utilize USB ports and HDMI.
  5. Programming and Interaction: You may write code to control the Raspberry Pi's I/O pins, interact with sensors and actuators, build projects, and even develop games and applications using your preferred programming language and libraries.

 

How to Control Raspberry Pi Remotely?
