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.
