Micro-bit microcomputers get new updates

The new models include speakers and microphones, as well as artificial intelligence and machine learning functions.

The former BBC-led project is now led by a foundation, which aims to make coding easy for children.

The equipment will be released next month and the price will start from 11.50.

Gareth stockdale, CEO of micro bit Education Foundation, said: "The purpose of Micro Bit is to help children release their creative potential and learn how to shape the world around them."

"Learning coding and computational thinking can increase their chances of life in the 21st century."

Global Impact

Since its launch, Bit Micro has been designed for education, with an estimated 25 million children in more than 60 countries learning computer skills on the device.

The previous model was launched in the UK in 2016, with the BBC giving away free microbits to seven year olds every year.

Now most middle schools use it, and primary schools, universities and libraries also use it.

"microbits have low floors and high ceilings, so you can make improvements if you want, but they can also be very basic, " said Keith Crile, a lecturer at the Technical University of Dublin, who runs free microbit courses for children and teachers.

"We teach it at the level of primary school and university degree-because you don't need many other tools to make it work, it is very easy to use."

The foundation has also donated 5000 devices to British families to help educate families during the coronavirus pandemic.

How it works

Micro Bit is a palm-sized circuit board consisting of an array of 25 lights that can be programmed to display letters, numbers, and other shapes, as well as a Bluetooth chip for wireless connectivity.

Instead of typing the code directly into the computer, users choose to write scripts in four programming languages through web-based tools on PC, or through apps on tablets or smartphones.

Once written, the compiled script must be transmitted to the micro-bit, and then the micro-bit as an independent device can be used to flash messages, record movements and other tasks.

It can also be connected to other electronic devices, forming the "brain" of a robot, musical instrument or other toolbox.

New features

The new model will include a better microprocessor with more memory; Built-in microphone and speaker; And touch sensors.

Built-in speakers will allow users to create music and create interactive motion-sensitive instruments.

The microphone will enable the device to respond to sound - for example, it can create a disco light that moves to music in time.

Since the hardware is now powerful enough to run machine learning systems, the foundation plans to expand into this area in the future.

"The simplicity of the microbit means it doesn't need any attachments, and now it has a speaker and microphone and it can do much more, " says Lorraine Underwood, author of saving the world and code.

“Children love things that are interactive, so adding a sound will enhance the learning experience.“
