A comparative review of robot cars with micro:bit and on features of new version of micro:bit

The micro:bit is an educational, inexpensive single board computer with many sensors. There are many lesson practices that use this alone, but when we combin with other equipment, we can use for various learning. A robot car is one of them. We made a comparative review of three robot cars in this treatise. Accordingly we found out that each robot car has its own characteristics in the program, so it is necessary to use properly depending on what we aim for. In addition, since new version of micro: bit was released in November, we overview of its characteristics and we make sure of becoming easier to use for learning.
