- Digital Input
2)Serial Monitor
3)Pressing button changes fading animation speed.
/* Fade with Button */ int led = 11; // the PWM pin the LED is attached to int brightness = 0; // how bright the LED is int fadeAmount = 1; // how many points to fade the LED by const int buttonPin = 7; // the number of the pushbutton pin const int ledPin = 11; // the number of the LED pin // variables will change: int buttonState = 0; // variable for reading the pushbutton status // the setup routine runs once when you press reset: void setup() { // declare pin 11 to be an output: pinMode(led, OUTPUT); // initialize the LED pin as an output: pinMode(ledPin, OUTPUT); // initialize the pushbutton pin as an input: pinMode(buttonPin, INPUT); } void loop() { // read the state of the pushbutton value: buttonState = digitalRead(buttonPin); // check if the pushbutton is pressed. // if it is, the buttonState is HIGH: if (buttonState == HIGH) { //if the button is pressed,increased fade amount by 1 fadeAmount = fadeAmount + 5; } // set the brightness of pin 11: analogWrite(led, brightness); // change the brightness for next time through the loop: brightness = brightness + fadeAmount; // reverse the direction of the fading at the ends of the fade: if (brightness <= 0 || brightness >= 255) { fadeAmount = -fadeAmount; } // wait for 10 milliseconds to see the dimming effect delay(10); }
Cool! Would you please post your code from your custom fade controlling experiment?
sure, I just updated it. sorry for that.
