BBC Micro Bit Smart Car

Description

This micro bit smart robot car is based on the Micro:bit development board. The car fully exploits the compact and aesthetic features of the Micro:bit development board, using a micro:bit dot matrix screen as the main body and using onboard Bluetooth as APP communication.

The micro: bit smart car integrates a passive buzzer on the expansion board. The buzzer can be programmed to play various song music. Users can also use the companion app to perform a remote piano play.

The micro:bit intelligent car is equipped with a customized infrared remote controller. The infrared remote control can be used to control the car's movement (forward, backward, left, right), turn the car lights on/off, and change the programming lights mode.

Key Features & Capabilities

• Tracking: The car can follow a designated line.
• Following: The car can follow a detected object.
• Obstacle Avoidance: Equipped with an ultrasonic sensor, the car can detect obstacles and turn to avoid them, with a typical detection range of 20cm.
• Cool Lights: Features customizable RGB lighting, including 10mm RGB and WS2812 RGB LEDs, allowing for dynamic visual effects.
