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() { pinMode(6,OUTPUT);// pwm pin 6 as output pi...
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. } The line of code starting with ‘pinMode’ sets pin 13 as an output. This enables us to write a value to...
