Project Car — LEGO SPIKE Prime RC Car

A LEGO SPIKE Prime car inspired by a TikTok video of someone’s project car. Built by a group of robotics scholars under my guidance for a school showcase.

Programs

Enhanced RC car with:

Two scholar modes: “good” (ultrasonic sensor on port C, green light) and “experiment” (no ultrasonic, red light)
Headlamp control: 4 modes via D-pad — Off, Front lights, Back lights, All lights
Obstacle warning: Ultrasonic sensor triggers controller rumble when within 100cm (intensity increases as distance decreases)
Port auto-detection: Scans ports for connected devices on startup
