/*Analog InputDemonstrates analog input by reading an analog sensor on analog pin 0 andturning on and off a light emittingdiode(LED) connected to digital pin 13.The amount of time the LED will be on and off depends on the value obtainedby analogRead().The circuit:- potentiometercenter pin ...
// put your main code here, to run repeatedly: 将主程序代码放这里,会重复运行: } 2、模拟串口读取 -Bare Minimum code needed This example contains the bare minimum of code you need for a sketch to compile properly on Arduino Software (IDE): thesetup()method and theloop()method. 该例包含...
This example code is in the public domain.此代码示例位于公共域中。arduino.cc/en/Tutorial/...int sensorPin = A0; // select the input pin for the potentiometer 选择电位器的输入针脚 int ledPin = 13; // select the pin for the LED 选择 LED 针脚 int sensorValue = 0; // var...
It's made up of a series of LEDs in a row, an analog input like a potentiometer, and a little code in between.它是由行系列的LED,像一个电位器的模拟输入,以及很少的代码之间。You can buy multi-LED bar graph displays fairly cheaply, like this one .你可以买多LED条形图显示相当便宜一样,...
code examples that make the robot move: (1) driveStraight (speed) (2) drive(speed, radius) (3) stop() (4) spinLeft(speed) (5) spinRight(speed) Please see the page after the code example for going straight based on the potentiometer value for a reference of all of these functions....
int analogPin = 3; // potentiometer connected to analog pin 3 int val = 0; // variable to store the read value void setup() { pinMode(ledPin, OUTPUT); // sets the pin as output } void loop() { val = analogRead(analogPin); // read the input pin ...
In Figure 4-14, you’ll see the organization of the code for a simple program to turn a light on and off when a button is pressed. There are three distinct elements to this program: initialization This element contains all the variables and values that will be used throughout the program...
County Library WARNING: Please read these instructions entirely before using the Arduino and components found in this kit. Plugging in components incorrectly can result in damage and possible injury. If any components begin to feel warm, unplug power source immediately and re-check your work.
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. */// the setup routine runs once when you press reset:void setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600...
Have a motor power supply that can deliver that current. Make sure the motor power supply voltage is within the range supported by the driver board. Set Max Current The max current is set via the potentiometer on board. Turn it while measuring voltage at the passthrough next to it. The fo...
