对于Arduino，用pinMode将IO口设为OUTPUT的时候，其实IO的状态为“强推挽”，也就是说设为高电平时，I...

int x ; // initialising variable x float Voltage ; // initialising variable voltage int I ; // this is the variable which changes in steps and hence changes resistanceaccordingly. void setup() { pinMode (CS , OUTPUT) ; // initialising 10 pin as output pin pinMode (A0, INPUT) ; //...
Write a HIGH or a LOW value to a digital pin. If the pin has been configured as an OUTPUT with pinMode(), its voltage will be set to the corresponding value: 5V (or 3.3V on 3.3V boards) for HIGH, 0V (ground) for LOW. 如果引脚被设置为INPUT,digitalWrite()会激活输入引脚的上拉电阻。
VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.The all...
voidsetup() {//The following code will be executed once when your Arduino turns on.pinMode(13, OUTPUT);//Set pin 13 as an 'output' pin as we will make it output a voltage.digitalWrite(13,HIGH);//This turns on pin 13/supplies it with 3.3 Volts.} ...
pinMode(fadePin,OUTPUT); // pin that will fade to your heartbeat! Serial.begin(115200); // we agree to talk fast! interruptSetup(); // sets up to read Pulse Sensor signal every 2mS // UN-COMMENT THE NEXT LINE IF YOU ARE POWERING The Pulse Sensor AT LOW VOLTAGE, // AND APPLY...
思维导图Mind mapping在Arduino中，模拟输入通常指的是通过Arduino的模拟引脚读取来自传感器、按钮或其他模拟设备的电压值。Arduino板上有多个模拟引脚（通常标记为A0-A5），可以用来读取模拟信号。In Arduino, analog input usually refers to the voltage value from the sensor, buttons, or other analog device ...
pinMode(ReadUVintensityPin, INPUT); Serial.begin(9600); //open serial port, set the baud rate to 9600 bps Serial.println("Starting up..."); } void loop() { int uvLevel = averageAnalogRead(ReadUVintensityPin); float outputVoltage = 5.0 * uvLevel/1024; ...
Let’s say this mapped value is 200. Then PWM voltage onpin 6 will be at: [ (200*5) / 255 ]= 3.921 volts 由于MOSFET是一个电压相关的器件,因此该PWM电压最终决定了负载两端的电压。 int x; // initialize variables int w; void setup() { ...
