Lesson 1: Motor Control¶

Goal / 目標¶

Understand motor numbering and control individual motors with PWM.

Motor Layout / モーター配置¶

API / 使用するAPI¶

Function	Description
`ws::motor_set_duty(id, duty)`	Set motor duty (id=1-4, duty=0.0-1.0)
`ws::motor_set_all(duty)`	Set all motors to same duty
`ws::motor_stop_all()`	Stop all motors

Steps / 手順¶

Switch to this lesson: sf lesson switch 1
Spin motor 1 at 10% duty
Verify which propeller spins (FR = front-right) / どのプロペラが回るか確認（FR = 右前）
Try each motor to confirm numbering / 各モータを試して番号を確認
WARNING / 注意: Hold the drone firmly! Do not exceed 15% duty! / 機体をしっかり押さえること！duty 15% を超えないこと！

Challenge / チャレンジ¶

Cycle through all 4 motors, spinning each for 2 seconds.
