Ok, I decided to make some LED's to go in a pumpkin this year. Here's the code for it:
/*
Pumpkin LED Lights
This sketch controls 6 LEDs connected to the 6
PWM pins
1&2 are Green
3&4 are Yellow
5&6 are Red
*/
int ledPin1 = 3; // LED connected to digital pin
int ledPin2 = 5; // LED connected to digital pin
int ledPin3 = 6; // LED connected to digital pin
int ledPin4 = 9; // LED connected to digital pin
int ledPin5 = 10; // LED connected to digital pin
int ledPin6 = 11; // LED connected to digital pin
// The setup() method runs once, when the sketch starts
void setup() {
// initialize the digital pin as an output:
pinMode(ledPin1, OUTPUT);
pinMode(ledPin2, OUTPUT);
pinMode(ledPin3, OUTPUT);
pinMode(ledPin4, OUTPUT);
pinMode(ledPin5, OUTPUT);
pinMode(ledPin6, OUTPUT);
randomSeed(analogRead(0));
}
// the loop() method runs over and over again,
// as long as the Arduino has power
void loop()
{
Flicker(random(1,4),random(2,200)); // might be a long flicker
Glow(random(1,4),random(5,40),random(2,30));
Flicker(random(1,4),random(200,800)); // long flicker
}
int Flicker(int col, int del){
unsigned long currentMillis = millis();
unsigned long startMillis = currentMillis;
do
{
if (col == 1) {
analogWrite(ledPin1, random(0, 255));
delay(10);
analogWrite(ledPin2, random(0, 255));
delay(10);
}
if (col == 2) {
analogWrite(ledPin3, random(0, 255));
delay(10);
analogWrite(ledPin4, random(0, 255));
delay(10);
}
if (col == 3) {
analogWrite(ledPin5, random(0, 255));
delay(10);
analogWrite(ledPin6, random(0, 255));
delay(10);
}
unsigned long currentMillis = millis();
}
while (millis() < (startMillis + (del * 1000)));
analogWrite(ledPin1, 0);
analogWrite(ledPin2, 0);
analogWrite(ledPin3, 0);
analogWrite(ledPin4, 0);
analogWrite(ledPin5, 0);
analogWrite(ledPin6, 0);
}
int Glow(int col, int cycles, int del){
if (col == 1) {
for (int u=1; u <= cycles; u++){
for (int i=0; i <= 250; i = i + 4){
analogWrite(ledPin1, i);
analogWrite(ledPin2, i);
delay(del);
}
for (int i=0; i <= 250; i = i + 4){
analogWrite(ledPin1, 255-i);
analogWrite(ledPin2, 255-i);
delay(del);
}
}
}
analogWrite(ledPin1, 0);
analogWrite(ledPin2, 0);
if (col == 2) {
for (int u=1; u <= cycles; u++){
for (int i=0; i <= 250; i = i + 4){
analogWrite(ledPin3, i);
analogWrite(ledPin4, i);
delay(del);
}
for (int i=0; i <= 250; i = i + 4){
analogWrite(ledPin3, 255-i);
analogWrite(ledPin4, 255-i);
delay(del);
}
}
}
analogWrite(ledPin3, 0);
analogWrite(ledPin4, 0);
if (col == 3) {
for (int u=1; u <= cycles; u++){
for (int i=0; i <= 250; i = i + 4){
analogWrite(ledPin5, i);
analogWrite(ledPin6, i);
delay(del);
}
for (int i=0; i <= 250; i = i + 4){
analogWrite(ledPin5, 255-i);
analogWrite(ledPin6, 255-i);
delay(del);
}
}
}
analogWrite(ledPin1, 0);
analogWrite(ledPin2, 0);
analogWrite(ledPin3, 0);
analogWrite(ledPin4, 0);
analogWrite(ledPin5, 0);
analogWrite(ledPin6, 0);
}
The basic setup is 6 LED's on the PWM pins, grouped in two's, so LEDs 1&2 are both green, 3&4 are yellow and 5&6 are red. It just goes through some basic effects. I could have done more but this is good enough for now.
