· shiftOut(dataPin, clockPin, bitOrder, value) SPI外部IO扩展函数,通常使用带SPI接口的74HC595做8个IO扩展,dataPin为数据口,clockPin为时钟口,bitOrder为数据传输方向(MSBFIRST高位在前,LSBFIRST低位在前),value表示所要传送的数据(0～255),另外还需要一个IO口做74HC595的使能控制。 · unsigned long pulseIn...
Arduino - Analog Keypad LibraryThis library is designed for the following use cases:The project uses a keypad but IO pins are not enough ⇒ use an Analog Keypad, which connects to a single analog input pin. The project uses multiple buttons but IO pins are not enough ⇒ build a button...
/*ButtonTurns on and off a light emitting diode(LED) connected to digital pin 13,when pressing a pushbutton attached to pin 2.The circuit:- LED attached from pin 13 to ground through 220 ohm resistor- pushbutton attached to pin 2 from +5V- 10K resistor attached to pin 2 from ground- ...
It’s not a full simulator like Tinkercad or Proteus—just a virtual Uno with digital and analog pins, plus basic I/O like LEDs, buttons, and potentiometers. Built for education, UNOArduSim shines in classrooms or solo study, letting you upload sketches and watch pin states shift in a s...
Arduino语言 Arduino语言是建立在C/C++基础上的,其实也就是基础的C语言,Arduino语言只不过把AVR单片机(微控制器)相关的一些参数设置都函数化,不用我们去了解他的底层,让我们不了解AVR单片机(微控制器)的朋友也能轻松上手。 在与Arduino DIYER接触的这段时间里,发
When the supply voltage is different, the analog value corresponding to the same button on the module is different. When using, we can’t press the multiple buttons in the same time; if you did, analog value read by the signal pin of the module is the minimum analog value corresponding ...

Just like the original Nintendo, the Arduino has a reset button(10). Pushing it will temporarily connect the reset pin to ground and restart any code that is loaded on the Arduino. This can be very useful if your code doesn’t repeat, but you want to test it multiple times. Unlike the...
