5, 6, 9, 10, and 11. On the Arduino Mega, it works on pins 2 through 13. Older Arduino boards with an ATmega8 only support analogWrite() on pins 9, 10, and 11. You do not need to call pinMode() to set the pin as an output before calling analogWrite(). ...
Arduino IDE自然是从官网下载的。pinMode(pin, mode):设置引脚。第一个参数表示设置的引脚,第二个参数表示将要把引脚设置成的模式。digitalWrite(pin, value):输出信号。第一个参数为引脚,第二个参数为输出模式。HIGH即为高电平,LOW即为低电平。 set
Full tutorial on how to control the Arduino UNO ports using register. Port register manipulation. Set pins as output/input DDRD, set pin to high or low PORTD, or read inputs with the PIN register.
