③在analogWrite() 和analogRead() 函数内部,已经完成了引脚的初始化,因此不用在Setup() 函数中进行初始化操作。 参数:参数pin是指定要输出PWM波的引脚;参数value指定是PWM的脉冲宽度,范围为0～255。 返回值:Arduino Uno模拟输入功能有10位精度,即可以将0～5V的电压信号转换为0～1023的整数形式表示。 eg.示例程序...
Arduino UNO的ADC分辨率为10位，意味着它可以区分0至1023之间的数值。参考电压：Arduino UNO的参考电压通常是5V，这意味着ADC的最大输入电压为5V，对应于ADC输出的最大数值1023。Model conversion: The process of converting analog signals (continuous voltage signals) into digital signals (discrete values). Resol...
The Uno has 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and the analogReference() fun...
These pins correspond to analog pins A4 (SDA) and A5 (SCL) on the Arduino Uno. Arduino ADC Specification Parameter Arduino Uno/Nano Voltage Supply (Vs) 1V8 ~ 5V5 Interface Built in Resolution 10 bit Absolute Accuracy(Including INL, DNL, ...
