Keyboard.begin();}这样在setup中写入这个就可以模拟键盘了,我写入这个之后,这个板子插到电脑上,就被电脑认为键盘了然后,用以下语录实现按下某键,和抬起某键,或者抬起它当然,数字对应的是ascII码,可以Baidu出对照表setup部分在板子接电后只运行一次。loop部分也被无限重复执行void loop() {Keyboard.press(56);...

The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. When we need to go small, we use a Metro Mini or a Trinket M0, but when size isn't as much of a concern, we reach for an Adafruit METRO. ...

Input Pullup Serial This example demonstrates the use of pinMode(INPUT_PULLUP). It reads a digital input on pin 2 and prints the results to the serial monitor. The circuit: * Momentary switch attached from pin 2 to ground * Built-in LED on pin 13 ...
Arduino Keyboard Input via Serial - Learn how to use the Arduino to read keyboard input through serial communication effectively. Explore practical examples and detailed instructions.
数字I/OpinMode(pin, mode) 数字IO口输入输出模式定义函数,pin表示为0～13, mode表示为INPUT或OUTPUT。 digitalWrite(pin, value) 数字IO口输出电平定义函数,pin表示为0～13,value表示为HIGH或LOW。比如定义HIGH可以驱动LED。 int digitalRead(pin) 数字IO口读输入电平函数,pin表示为0～13,value表示为HIGH或LOW。
