BitCar is a micro:bit project that designs a smart, programmable robot car to encourage kids’ STEAM learning. After combining programs from Microsoft MakeCode, the robot car will be able to perform line following, obstacle avoidance and even a wheelie. The car carries a speaker itself for playing melodies and sound effect, and has 4 colorful RGB LEDs on the underside of it and a detachable ultrasonic sensor in the front for avoiding obstacles on the way.
