How Smart Car Kits Achieve Infrared Line Tracking Function
Learn how infrared sensors enable line tracking in smart car kits. Covers working principle, coding logic with Micro:bit, common issues, and creative extensions.
Black line tracking is currently the most common function of entry-level programmable smart car kits. This function is mainly realized based on infrared line-tracking sensors.
At present, common line-tracking sensors on the market include two-channel, three-channel, four-channel, and eight-channel infrared line-tracking sensors. They are respectively suitable for smart cars of different sizes, as well as different application scenarios.
