引脚(pins)配置为输入(inputs)arduino(atmega)引脚通过pinmode()配置为 输入(input) 即是将其配置在一个高阻抗的状态。配置为input的引脚可以理解为引脚取样时对电路有极小的需求,即等效于在引脚前串联一个100兆欧姆(megohms)的电阻。这使得它们非常利于读取传感器,而不是为led供电。引脚(pins)配置为输出(outputs...
Acquire inputs and send outputs to Arduino® hardware including entry-level boards, MKR, Nano families and ESP32 modulesMATLAB® Support Package for Arduino Hardware enables you to use MATLAB to communicate with several Arduino boards under the entry-level series, MKR, and Nano families of Ard...
At its core, Arduino is a development board equipped with various inputs and outputs, allowing users to interact with the physical world. It can sense and control objects and devices through analog and digital signals, making it an excellent tool for building interactive projects. ...
Initializes the SPI bus by setting SCK, MOSI, and SS to outputs, pulling SCK and MOSI low, and SS high. SyntaxSPI.begin() ParametersNone ReturnsNone end()关闭SPI总线 Description Disables the SPI bus (leaving pin modes unchanged).

a Analog inputs. b Digital I/O. c Pulse-width modulation outputs (alternate DIO pin functions). Arduino USB Interfaces Starting with the Leonardo board (2012), the ATmega32U4 XMEGA microcontroller has been used as the primary processor. This part has a built-in USB interface, which eliminate...
Notes and Known Issues 备注和已知问题 The PWM outputs generated on pins 5 and 6 will have higher-than-expected duty cycles. This is because of interactions with the millis() and delay() functions, which share the same internal timer used to generate those PWM outputs. This will be noticed...
