INTRODUCTION:
Micro:bit is a user-friendly, beginner-friendly microcontroller usually designed for educational purposes. Typically, it is designed for children to improve their thinking abilities. The micro:bit is widely used in schools to teach programming, electronics, and computational thinking.
Children, with their keen eye for vibrant colours and a penchant for fun, gravitate toward products that exude playfulness. Just as children’s books burst with hues and whimsical illustrations, the micro:bit—a delightful pocket-sized computer—embraces this same spirit.
Its rainbow of card colours and twinkling LEDs captivates not only young minds but also those of us who secretly yearn for a touch of magic in our tech.
Next, we have Arduino, which is a versatile microcontroller platform with a wide range of hardware options. Usually, its design is boring for children.
The Arduino appeals to a niche market of seasoned robotics enthusiasts who have reached mid- and high-expertise levels. Its plain, flat colour and practical pins for inputs and outputs are its distinguishing features. Maybe the wise Arduino founders decided that this talented group didn't need a lot of customization.
What is micro:bit ?
A micro:bit is a pocket sized computer designed for Children for the educational purpose.
Here are the components in it:
- LED Light Display: The micro:bit has a 5x5 grid of LEDs that can display text, images, and animations.
- Buttons: It has two programmable buttons (A and B) for user interaction.
- Sensors: The micro:bit includes an accelerometer, a compass, and a light sensor.
- Bluetooth Antenna: It supports wireless communication via Bluetooth.
- Input/Output Pins: It has GPIO pins for connecting external components.
- Sound Sensing and Playback in the latest version.
We can program micro:bit using various programming languages like – JavaScript, MicroPython, Microsoft MakeCode. micro:bit supports block coding and text-based coding in Python.
Especially the Makecode IDE developed by Microsoft is a very comprehensive and useful block-based coding program.
What is an Arduino?
An Arduino is an open-source platform which has the combination of both software and hardware.
Here are the components in it:
- Microcontroller: It acts as the brain of an Arduino, responsible for executing programs. It’s like a tiny computer designed for doing specific tasks.
- USB Port: Used to connect the Arduino board to your computer for programming and communication.
- Digital Pins: These pins can be used for input/output tasks.
- Analog Pins: These pins allow you to read analog signals, such as sensor values or variable voltages.
- Power Pins: These include power supply pins [orange] and ground pins [light orange].
- Reset Button: Pressing this button resets the microcontroller.
- Crystal Oscillator: Provides precise timing for the microcontroller.
Arduino is programmed with C/C++, and it is more technical and complicated programming language. This can be challenging for beginners and children.
