Reads an analog input on pin 0, prints the result to the serial monitor. Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground. This example code is in the public domain. */ 功能:读取模拟输入引脚A0的值,并将其打印到串行监视器。 硬件连接:将电位...
This example shows you how to read analog input from the physical world using a potentiometer. Apotentiometeris a simple mechanical device that provides a varying amount of resistance when its shaft is turned. By passing voltage through a potentiometer and into an analog input on your board, it...
Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu). Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground. This example code is in the public domain. https://www.arduino.cc/en/Tutorial/BuiltInExamples/ReadAnalogVolta...
For example: int sensorvalue = analogRead(A2);. The function is used to program and address analog pins on the Arduino board and will also return the analog input reading which is between 0 to 1023. How to use Meausre Analog Signal? Let’s connect a potentiometer or variable resistor to ...

AnalogInOutSerial - 读取一个模拟输入引脚,按比例划分读数,然后用这个数据来熄灭或者点亮一个LED灯 AnalogWriteMega - 用一个Arduino或者Genuino Mega开发板来使12个LED灯一个接一个逐渐打开和熄灭 Calibration - 定义期望中的模拟传感值的最大值和最小值 ...
Blink: 使一个LED灯开关. DigitalReadSerial: 读取引脚,打印状态到Arduino串口监视器 AnalogReadSerial: 读取一个电位计,打印它的状态到Arduino串口监视器 Fade: Demonstrates 示范用模拟输出使LED灯亮度变淡 ReadAnalogVoltage : 读取一个模拟输入,然后打印其电压值到串口监视器...
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Arduino示例，演示如何使用模拟引脚读取来自某个传感器的输入：The following is a simple Arduino example. Demonstration of how to use analog pins to read the...
This example shows how to fade an LED on pin 9 using the analogWrite() function. The analogWrite() function uses PWM, so if you want to change the pin you're using, be sure to use another PWM capable pin. On most Arduino, the PWM pins ...
ReadAnalogVoltage 在PIN 0上读取模拟输入,将其转换为电压,并将结果打印到串行监视器。 图形表示可使用串行绘图仪(工具>串行绘图仪菜单)。 将电位器的中心销连接到销A0,外引脚连接到+5V和接地。 This example code is in the public domain. http://www.openmaker.cn ...
