Arduino IDE 上附带的文件 > 示例 > 03.Analog > Fade示例,展示了如何通过analogWrite()函数,以 PWM 模拟输出的方式控制 LED 的淡入淡出(渐亮与渐暗)。 intledPin=9;// LED 正极连接至数字 D9 引脚,而负极连接到 GNDvoidsetup(){// 不需要进行任何设置}voidloop(){/* 淡入,从最暗到最亮,每次增加 5...
AnalogInOutSerial - 读取一个模拟输入引脚,按比例划分读数,然后用这个数据来熄灭或者点亮一个LED灯 AnalogInput - 用电位计来控制LED灯闪烁 Calibration - 定义期望中的模拟传感值的最大值和最小值 Fading - 用模拟输出(PWM引脚)来使LED灯变亮或者变暗 Smoothing - 使多个模拟输入引脚的读取值变得平滑...

There are 16 analog pins incorporated on the board labeled as A0 to A15. It is important to note that all these analog pins can be used as digital I/O pins. Each analog pin comes with 10-bit resolution. These pins can measure from ground to 5V. However, the upper value can be chang...
wokwi-arduino-mega参考 Arduino Mega 2560。由ATmega2560芯片提供支持,该芯片拥有256K字节的Flash程序内存、8k字节的SRAM和4K字节的EEPROM。该板具有54个数字引脚、16个模拟输入引脚和4个串行端口。它以16MHz运行。 引脚名称 引脚0到53是数字GPIO引脚。引脚A0至A15除了是数字GPIO引脚外,还兼作模拟输入引脚。
