I have 2 sketches which work perfectly on their own but cannot merge the 2 for a perfect sketch.
The first sketch is for PIR sensor and the second is for a LED chaser.
sketch1
/* KnightRider
*/
const int NbrLEDs = 8;
const int ledPins[] = {2, 3, 4, 5, 6, 8, 9, 10}; const int wait = 100;
void setup(){
for (int led = 0; led < NbrLEDs; led++)
{
pinMode(ledPins[led], OUTPUT);
} }
void loop() {
for (int led = 0; led < NbrLEDs-1; led++)
{
digitalWrite(ledPins[led], HIGH); delay(wait);
digitalWrite(ledPins[led + 1], HIGH); delay(wait); digitalWrite(ledPins[led], LOW); delay(wait*2);
}
for (int led = NbrLEDs; led > 0; led--) {
digitalWrite(ledPins[led], HIGH); delay(wait);
digitalWrite(ledPins[led - 1], HIGH); delay(wait); digitalWrite(ledPins[led], LOW); delay(wait*2);
} }
sketch2
/////////////////////////////
//SETUP
void setup(){
Serial.begin(9600);
pinMode(pirPin, INPUT);
pinMode(ledPin, OUTPUT);
digitalWrite(pirPin, LOW);
//give the sensor some time to calibrate
Serial.print("calibrating sensor ");
for(int i = 0; i < calibrationTime; i++){
Serial.print(".");
delay(1000);
}
Serial.println(" done");
Serial.println("SENSOR ACTIVE");
delay(50);
}
////////////////////////////
//LOOP
void loop(){
if(digitalRead(pirPin) == HIGH){
digitalWrite(ledPin, HIGH); //the led visualizes the sensors output pin state
if(lockLow){
//makes sure we wait for a transition to LOW before any further output is made:
lockLow = false;
Serial.println("---");
Serial.print("motion detected at ");
Serial.print(millis()/1000);
Serial.println(" sec");
delay(50);
}
takeLowTime = true;
}
if(digitalRead(pirPin) == LOW){
digitalWrite(ledPin, LOW); //the led visualizes the sensors output pin state
if(takeLowTime){
lowIn = millis(); //save the time of the transition from high to LOW
takeLowTime = false; //make sure this is only done at the start of a LOW phase
}
//if the sensor is low for more than the given pause,
//we assume that no more motion is going to happen
if(!lockLow && millis() - lowIn > pause){
//makes sure this block of code is only executed again after
//a new motion sequence has been detected
lockLow = true;
Serial.print("motion ended at "); //output
Serial.print((millis() - pause)/1000);
Serial.println(" sec");
delay(50);
}
}
}
What I would like to know - is it possible to combine these two sketches?
All input and help appreciated.
