Example Code for Starting Maqueen Plus V3

Introduction

In this example, the Maqueen Plus V3 moves forward at a speed of 100. Additionally, the vehicle lights flash at a frequency of one second. The motor driving and vehicle light control blocks are used.

• The valid speed range is 0–255 (corresponding to PWM pulse width), not 0–100.
• If the speed is set below 30, the car may not move due to insufficient driving force from the PWM-driven motors. It is recommended to use speeds above 30.
• The vehicle lights are RGB LEDs. In this program, they are controlled in on/off mode, displaying only red.

Hardware Preparation

• Maqueen Plus V3 robot
• micro:bit (V1 or V2)
• USB cable for programming

Software Preparation

• MakeCode Editor for micro:bit
• Maqueen Plus V3 extension installed in MakeCode

Wiring Diagram
