The ELECFREAKS Ring:bit Car Accessories pack contains three dedicated modules designed for the Ring:bit Car V2: a tracking module, an LED light-bar module and a Sonar:bit ultrasonic sensor. The Ring:bit Car V2 and micro:bit are not included.
Modules
Tracking module: double infrared probes detecting at 2–12mm, for line following around circles, black-line detection and edge detection.
LED light-bar module: 8 rainbow full-colour LEDs, for auto-headlights and rainbow light effects.
Sonar:bit: ultrasonic sensor with a 4–400cm measurement range and ±1cm tolerance. Its 3-wire design uses one fewer IO port than a standard 4-wire ultrasonic module. Mounts at the back of the car for obstacle avoidance.
