The microcontroller of the board has a circuit inside called ananalog-to-digital converterorADCthat reads this changing voltage and converts it to a number between 0 and 1023. When the shaft is turned all the way in one direction, there are 0 volts going to the pin, and the input value ...
Arduino Mega 2560的数字IO引脚编号从0到53，其中0和1通常用于串行通信，而一些引脚还支持PWM输出。基本输入输出操作：输入操作：要将一个引脚设置为输入，可以使用pinMode函数，其中pin是你想要设置为输入的引脚编号。之后，可以使用digitalRead函数读取该引脚的电平状态。输出操作：要将一个引脚设置为输出，...

I connected a small LED to pin 11 to see the results of the above PWM code sample. As expected, it operates at a reduced brightness due to the lower voltage. The ‘127’ is a number that can range from 0 to 255, with 255 being the brightest setting. You can use this to set the...
这是一个抽象函数，其作用是向指定的数字量接口写入数据。在这个例子中，要写入的数字量接口是LED对应的管脚，写入的数据是目标状态，亮或灭。
In Arduino, analog input usually refers to the voltage value from the sensor, buttons, or other analog device through the analog pins of Arduino. There are multiple simulation pins on the Arduino board (usually marked as A0-A5), which can be used to read analog signals.以下是一个简单的...
在 Arduino 程序中，digitalWrite(LEDpin, state) 是一个函数，用于将电平写入数字引脚。该函数有两个参数：- LEDpin：数字引脚的编号。- state：布尔值，表示要写入的电平。如果 state 为 HIGH，则表示将高电平写入引脚；如果 state 为 LOW，则表示将低电平写入引脚。因此，digitalWrite(LEDpin, state...
