Question

A button is connected to p1.0 and an LED is connected to P2.0. Write code with PWM so that if the button is pressed the LED is on 70%, but if the button is not pressed the LED is on 10%

Answer 1

Semantic Network non-pressed BUTTON Iconnected to PIN Code int button-1 buttonStateLOW C should cause LED connected to ] PIN 2 Code int led 2 to emit LIGHT showing BRIGHTNESS 10% Code analogWrite(led, npressedBrightness) for 10% duty cycle, brightness 25 ( for 100% duty cycle, brightness-255)

pressed BUTTON .. [connected to ] PIN Code int button-1 buttonState HIGH Cshould cause CLED connected to PIN 2 ode Code int led-2 cto emit C LIGHT cl-LIGHT showing] BRIGHTNESS 70 % Code analogWrite(led, pressedBrightness) for 70% duty cycle, brightness 178 .

int button = 1;
int led = 2;

int buttonState = 0;
int npressedBrightness = 25;
int pressedBrightness = 178;

void setup () {
pinMode(led,OUTPUT);
pinMode(button, INPUT) ;
}

void loop() {
  
   buttonState = digitalRead(button);
  
   if (buttonState == HIGH) {
       analogWrite(led, pressedBrightness);
   }
  
   else {
       analogWrite(led, npressedBrightness);
   }
    delay(30);
}
