trying 2 loops

Hi all, newbie to arduino here. I was eperimenting with some different functions and i found this: Idea is pretty basis but yet i’m stuck. Void loop works seperatly but when i try to add scheduler for void loop2 (line28) i get an error saying 'expected unqualified-id before ‘.’ token.
I only am trying to blink led on pin 1 seperate from the main loop for a project i am planning. Hope some can give me advice ! Thx.


#include <Scheduler.h>

//the time we give the sensor to calibrate (10-60 secs according to the datasheet)
int calibrationTime = 30;

//the time when the sensor outputs a low impulse
long unsigned int lowIn;

//the amount of milliseconds the sensor has to be low
//before we assume all motion has stopped
long unsigned int pause = 5000;

boolean lockLow = true;
boolean takeLowTime;

int pirPin = 7; //the digital pin connected to the PIR sensor’s output
int ledPin = 8;

void setup(){
pinMode(pirPin, INPUT);
pinMode(ledPin, OUTPUT);
pinMode(1, OUTPUT);
digitalWrite(pirPin, LOW);

//give the sensor some time to calibrate
Serial.print(“calibrating sensor “);
for(int i = 0; i < calibrationTime; i++){
Serial.println(" done");
Serial.println(“SENSOR ACTIVE”);

void loop(){

if(digitalRead(pirPin) == HIGH){
digitalWrite(ledPin, HIGH); //the led visualizes the sensors output pin state
//makes sure we wait for a transition to LOW before any further output is made:
lockLow = false;
Serial.print(“motion detected at “);
Serial.println(” sec”);
takeLowTime = true;

if(digitalRead(pirPin) == LOW){
digitalWrite(ledPin, LOW); //the led visualizes the sensors output pin state

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”);

void loop2() {
digitalWrite(1, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(1, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second

check the "blink without delay" example how to merge multiple pieces of code without the use of the BLOCKING delay function.

The demo several things at a time is an extended example of the BWoD technique.


thanks for your guidance, code is working now! on to the next challenge :slight_smile:
