Materials:

• Micro:bit board
• Micro:bit battery pack
• 2 small DC motors
• Wheels for the motors
• Motor driver board (such as L293D)
• Jumper wires
• Chassis or materials to build one (cardboard, plastic, 3D printed parts, etc.)
• Screws, nuts, and bolts (if building a chassis)

• Steps:

• Begin by assembling the chassis or structure for your car. You can use cardboard, plastic, or 3D printed parts to create a frame. Make sure to leave space for the Micro:bit and battery pack.

• Connect the motor driver board to the Micro:bit using jumper wires. Refer to the pinout diagram for the Micro:bit and the motor driver board.

• Connect the DC motors to the motor driver board using jumper wires. Be sure to connect the wires to the correct terminals on the board.

• Attach the wheels to the motors.

• Power the Micro:bit using the battery pack.

• Write the code to control your car using the Micro:bit's programming language, either using a web-based editor like MakeCode or a text editor like MicroPython.

• Test your code and make adjustments as needed.

• Once your car is working, you can add additional features, such as sensors or LEDs.

• With a bit of creativity and experimentation, you can create a wide range of Micro:bit cars with different shapes, sizes, and features. Some examples of Micro:bit cars include line-following robots, obstacle-avoiding robots, and remote-controlled cars.
