{"title":"BITCAR - Autonomous Line Following  Obstacle Avoiding Car for micro:bit","handle":"bitcar-autonomous-line-following-obstacle-avoiding-car-for-micro-bit","url":"/products/bitcar-autonomous-line-following-obstacle-avoiding-car-for-micro-bit","description":"The BitCar is a micro:bit-powered robot car kit featuring autonomous line following, ultrasonic obstacle avoidance, and remote control capabilities. Built around a sturdy chassis with two metal gear motors, the car includes built-in modules for buzzer, line follower, and four addressable RGB LEDs — ready to program straight out of the box.\n\nTwo spare Grove connection ports on the underside (one I²C, plus P1 and P2) allow advanced users to add sensors and modules for extended functionality. Program the car using Microsoft MakeCode's drag-and-drop block editor or text-based JavaScript. A micro:bit board is required but not included.\n\nKey Features\n\n\nLine Following – Built-in line follower sensor for autonomous path tracking\n\nObstacle Avoidance – Ultrasonic sensor detects and navigates around obstacles\n\nRemote Control – Wireless control via a second micro:bit or compatible controller\n\nBuilt-In Buzzer – Programmable audio feedback and sound effects\n\n4 Addressable RGB LEDs – Individually controllable colour lighting\n\n2 Grove Expansion Ports – Add sensors and modules for advanced projects\n\nCustomisable Design – Flat acrylic surfaces for stickers, tape, or laser-cut modifications\n\n\nSpecifications\n\n\nPower Supply – 3× AAA batteries (not included)\n\nWorking Voltage – 5 V\n\nWorking Current – 1.5 A max\n\nMotors – 2× metal gear motors\n\nLEDs – 4× addressable RGB\n\nExpansion – 2× Grove ports (1× I²C, 1× P1/P2)\n\nPackage Dimensions – 170 × 90 × 60 mm\n\nWeight – 100 g\n\nRecommended Age – 8+\n\n\n\nNote: A micro:bit board is required to use this kit and is not included.
