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...

Let’s say this mapped value is 200. Then PWM voltage on pin 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() { pinMode(6,OUTPUT);// pwm pin 6 as output ...
引脚（pin）是对芯片的外部物理接口的一个称呼，它是在不把这个物理接口投入到具体应用场合下的称呼。例...
It is the input voltage supplied to the board which ranges from 7V to 20V. The voltage provided by the power jack can be accessed through this pin. However, the output voltage through this pin to the board will be automatically set up to 5V. ...
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. } ...
Supply voltage: DC5V Output operation: Normally open(O) Output: DC three-wire system(NPN) 机械特性: 颜色:橙黄色 直径:18MM 长度:45MM 引线长度:18CM Diameter: 18mm, Length: 45mm Appearance: Threaded cylindrical Material: Plastic Guard mode: Reverse polarity protection ...
voidsetup(){pinMode(13,OUTPUT);}voidloop(){digitalWrite(13,HIGH);// turn the LED on (HIGH is the voltage level) delay(1000);// wait for a second digitalWrite(13, LOW);// turn the LED off by making the voltage LOW delay(1000);// wait for a second } ...
映射的0-5V可以从标记为Voltage的中间部分获得。然后可以将该映射电压反馈到Arduino模拟引脚。接下来我们...
