Can some one please send me an arduino program which alternates led brightness

Question

ardino

Answer 1

You can use pwm for that.
Call analogWrite(255) on you digital output pwm pin.
The value can be between 0 - 255 which is 0 - 5v.

analogWrite(127) means that the pwm duty cycle is 50% and the output voltage is 2.5V.

int brightness = 255;
int pwm = 6;
void setup {
pinMode(pwm, OUTPUT)
}
void loop {
analogWrite(pwm, brightness);
brightness = brightness - 1;
if(brightness == 0) {
brightness = 255;
}
}

You could also connect a potentiometer to your analog input.

void loop() {
analogWrite(pwm, analogRead(A0));
}

Please note that analogRead() returns a value between 0 and 1023.
