Hands on with the new Micro Bit

The BBC has revealed the final design of the Micro Bit, a pocket-sized computer set to be given to about one million UK-based children in October.

The device - which features a programmable array of red LED lights - includes two buttons and a built-in motion sensor that were not included in a prototype shown off in March.

But another change means the product no longer has a slot for a thin battery.

That may compromise its appeal as a wearable device.

Technology correspondent Rory Cellan-Jones went hands-on with the device at the launch event to see what it was capable of.
