BitCar is a micro:bit based do-it-yourself robot designed for STEM education. It’s easy to assemble, easy to code and fun to play with. The car uses two high quality metal gear motors to drive the wheels. The car's main electronics board integrates a buzzer for music or audio signals, 2 line follow sensors for tracking lines, and the 4 addressable LEDs on the bottom can be used as indicators, highlights or simply for cool decorations. There are also Grove connectors for add-ons like ultrasonic sensor, temperature sensor, light sensor, speech recognizer or other displays. All features of BitCar can be easily controlled with Microsoft MakeCode editor.

BitCar is one of TinkerGen’s most popular micro:bit project kits.  

The car constructed from the kit not only includes functions like line following, obstacle avoidance and remote control, but can also do a wheelie with the help of inertia! Show me another DIY car that can do this!

The car is composed of one chassis, two metal gear motors, two wheels and one acrylic cover. These components assemble to make a fantastic micro:bit car.

The chassis has a collection of useful modules built in, such as the buzzer, line follower and programmable RGB LEDs. To encourage further exploration, two spare connection ports are included on the underside of the chassis so kids can connect additional Grove modules like a proximity sensor, temperature sensor or speech recognition module to the car.

If you haven't heard of Grove before, Grove is a Seeed series which you can read more about here.

If you want to implement a remote-controlled car, we recommend that you also buy the BitPlayer. BitPlayer is the game controller from our micro:bit series which incorporates a 2-axis joystick and 6 programmable buttons, in the shape of a typical game controller, empowering kids to achieve an awesome project design experience.

If you don't have a micro:bit, click here to buy one.
