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...
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...

values). Resolution: ADC can distinguish the minimum analog signal change. Arduino Uno's ADC resolution is 10 bits, which means that it can distinguish the value between 0 and 1023. Reference voltage: The reference voltage of Arduino UNO is usually 5V, which means that the maximum input ...
PWM: 引脚 2 to 13使用analogWrite()函数提供8位的 PWM 输出. 可以通过analogWriteResolution() 函数改变PWM输出精度。 SPI: SPI接口 (在其他arduino上称作ICSP接口) 可以通过SPI库是SPI接口用于通信。SPI 引脚已经引出到了6针接口位置, 可以和 Uno、Leonardo、Mega2560兼容. 这个SPI针仅用于和其他SPI设备通信,不能...
I have a problem(does not work analog and digital inputs in model of Simulink(Arduino Uno)...constantly shows "0" on Scope( What can I do ?? 댓글 수: 1 Kaustubha Govind2014년 3월 27일 Which Arduino package are you using? There are several out there. Did you download a...
The Arduino Uno can be programmed with the (Arduino Software (IDE)). Select "Arduino/Genuino Uno from the Tools > Board menu (according to the microcontroller on your board). For details, see the reference and tutorials.∙On Rev1 boards: connecting the solder jumper on the back of the...
