I'm trying to set-up a sketch and don't know where to start.
I want to have a PIR trigger multiple LEDs (using multiple pins) and as PIR continues to be triggered the light increases to brighten area being covered.
*I would really like to have a new set of LEDs come on as motion continues, but will be satisfied with all LEDs getting brighter with continued motion.
I've tried book, Arduino cookbook, using Google and cannot find sketch or basic foundation to build on.
Please help.

Found a fix;
https://www.geeetech.com/2012/07/reinstall-arduino-bootloader-using-arduino-as-isp/

worked 1st time for me

thx for help and quick response from everyone

Does not ship to U.S., good idea though.

Thanks, will buy one in a few days.

I'm stuck with 10 328P chips with no bootloader loaded on them prior. Is there a simple, step-by-step instruction with illustrations as to where to place wires. Searching the web there are 100's of ways to do it, and have yet to find one that works. Emphasis on actually works. All the instruction on this site (arduino.cc) seem to end in no communication between Uno or Duemilanove and breadboard set-up. I've trip Uno-to-uno, Duemilanove-to-Uno, Mega-to-Uno....nothing works.
Please help and no flaming that there are resources out there already, I've tried. Simple instructions and point me in the right direction.
Thank you

I found following and want to modify it to handle 6+ ledpins.

byte SWITCHPIN= 2; //Set Pin 2 as Switch
byte LEDPIN = 6; //Set Pin 6 as LED
byte brightness; //Create a Integer variable named brightness
byte delayedoff; //Create a Integer variable named delayedoff
byte delayedon; //Create a Integer variable named delayedon

{
buttonstate = digitalRead(SWITCHPIN); //Continually look at the switch to see if its pressed
if (buttonstate == HIGH) //If the switch goes HIGH, act on it
{
crazyLED(); //Now we go into a new function called crazyLED
}
}
 
void crazyLED()//crazyLED function we created and called whatever we want
{
buttonstate = LOW; //First we tell the micro the switch is now LOW
delay(250);
while (buttonstate == LOW) //White the switch is NOT pressed we do the following
{
buttonstate = digitalRead(SWITCHPIN); //Continually look at the switch to see if its pressed
brightness = random(1, 254); //Generates a random number from 1-254 and assigns it to the variable named brightness
delayedoff = random(1, 125); //Generates a random delay and assigns it to the variable named delayed
delayedon = random(1, 250); //Generates a random delay and assigns it to the variable named delayed
analogWrite(LEDPIN, brightness); //Uses the random number we generated to write the value to our LED
delay(delayedon); //random delay on time
analogWrite(LEDPIN, 0); //We turn the LED off for a blinking effect
delay(delayedoff); //Random delay off time
}
//Once the switch is pressed again we break out of the loop above and then break out of the function completely and go back to our main loop
buttonstate = LOW; //First we tell the micro the switch is now LOW
analogWrite(LEDPIN, 0); //We turn the LED off before leaving our custom function
delay(500);
}

Thank you very much for any help you can give.

I was wondering how I can work a pseudorandom long integer into sketch using:
long randnum = random(0, 100); //a number between 0 and 99

Thanks

Is there a simple way of telling me how to integrate random numbers for length of LED being lit/unlit? I see the code in Getting Started With Arduino (p108) and I have no idea where to put it. I want to do the same as original post, each LED different value with random numbers.
I have following code to try to work into sketch:
long randnum = random(0, 100);

Thank you
