Example Code for Car Turning and RGB Light Control

Introduction

This example demonstrates how to control turning by setting different speeds for left and right motors. It also showcases advanced RGB lighting:

• Bottom RGB strip (connected to P1 on V3, unlike P15 on V2) uses rainbow color mode (hue range: 1–360).
• Front vehicle lights display two distinct RGB colors using V3’s enhanced color control.
• If using micro:bit V2, the built-in buzzer can be activated via the onboard speaker block.

Hardware Preparation

• Maqueen Plus V3
• micro:bit V2 (optional, for buzzer demo)
• USB cable

Software Preparation

• MakeCode with Maqueen Plus V3 extension
• Ensure correct pin assignment (P1 for bottom RGB on V3)

Wiring Diagram

All components are integrated. No external wiring needed.

Key Features:

• Left motor: speed 50 forward; Right motor: speed 0 → gentle right turn
• Bottom RGB: set rainbow hue block with dynamic hue value
• Front lights: individually set to different RGB values
• Optional: music.playSound(...) for micro:bit V2 buzzer

Result

• Robot performs smooth turns based on differential motor speeds.
• Bottom RGB strip cycles through vibrant rainbow colors.
• Front lights glow in two custom colors simultaneously.
• (If V2) Buzzer emits sound when triggered.
