These aren't connected with microbits but are excellent for simple sequencing tasks / challenges:
The bluetooth version is a little more expensive but worth it: it can then be programmed from a tablet, phone or pc using bluetooth. Each command can also be associated with a sound/message you can record which adds some extra fun or for accessibility needs. The Blue Bots can also be programmed by pressing buttons on the top of them. Mats are available and each forward movement covers one square of the mat.
They will detect if they are near another Blue Bot to say hello.
