The Arduino has always been used to control motors. A few examples would be the DC motor, servo motor, and stepper motor. Today, we are going to cover 2 motors, DC and Servo Motor, which are widely being used by many electronic hobbyists and makers due to their simplicity and functions...

The sketch we just used can be modified to do that. You’ll note some instructions in the remarks at the beginning of the code. Before you run the next sketch, you must prepare your image. It will need to be correctly sized to fit onto the display, and it will also have to be ...
舵机初始化:使用servo_init()对一组通道进行初始化,ESP32 包含LEDC_LOW_SPEED_MODE和LEDC_HIGH_SPEED_MODE两组通道,有些芯片可能只支持一组。初始化配置项主要包括最大角度、信号频率、最小输入脉宽和最大输入脉宽,用于计算角度和占空比的对应关系;引脚和通道用于分别指定芯片引脚和 LEDC 通道的对应关系; ...
