Arduino内置教程-模拟

模拟

  • 模拟输入输出串口：读取一个模拟输入引脚，返回结果，然后用这个数据使LED灯变暗或者变亮
  • 模拟输入：使用一个电压计来控制LED灯的闪烁
  • 模拟写入Mega：使用Arduino Mega 开发板使12个LED灯一个接一个，逐渐变亮然后变暗
  • 校准：对于超出模拟传感器范围的数值，定义一个最大值和最小值
  • 渐变：用一个模拟输出引脚（PWM引脚）来使一个LED灯褪色。
  • 使光滑：使多个模拟引脚的读取值变得顺滑

Analog In Out Serial: Read an analog input pin, map the result, and then use that data to dim or brighten an LED.
Analog Input: Use a potentiometer to control the blinking of an LED.
Analog Write Mega: Fade 12 LEDs on and off, one by one, using an Arduino Mega board.
Calibration: Define a maximum and minimum for expected analog sensor values.
Fading: Use an analog output (PWM pin) to fade an LED.
Smoothing: Smooth multiple readings of an analog input.
