OK, looking at the LED fade code It looks a lot like the blink tutorial with what looks like a slower turn on. I am playing with the code and would like to see the LED turn on slower, that is with more steps, but fadeamount only goes up to 5?
Thanks
/*
Fade
This example shows how to fade an LED on pin 9
using the analogWrite() function.
This example code is in the public domain.
*/
int led = 13; // the pin that the LED is attached to
int brightness = 0; // how bright the LED is
int fadeAmount = 5; // how many points to fade the LED by
// the setup routine runs once when you press reset:
void setup() {
// declare pin 9 to be an output:
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
// set the brightness of pin 9:
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 30 milliseconds to see the dimming effect
delay(30);
}
I see, I should look at the pinout for the chip! I am new and as usual want to rush into it. I have a resistor soldered to a LED and thought I would use the pin closest to the gnd pin so I could just shove it right into the Arduino board
Thanks all, will go back and try it in the correct pins!
Spend some time browsing the Arduino main site pages and build yourself a set of bookmarks. You will find gems like pin maps and a link to the AVR C++ libraries.
Get the Reference, Libraries, Examples/Tutorials, Foundations, Hacking and tour the Playground.
It's quite a mix and yet not comprehensive, you might find you need links off-site as well.
