Hi friends. I want to converting the second to hour. the V20 is slider widget to change the x time from 1 to 10 but its only second and will not converting to minute. Iām adding this code countDown = x * 3600L * 1000 but it cannot reach 128 second. thanks if helping me.
the sketch:
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <SimpleTimer.h>
const byte pirPin = 14;
const byte relayPin = 15;
const byte yellowledPin = 13;
const byte greenledPin = 12;
const byte calibrationTime = 5;
boolean alarmState = 0;
byte countDown = 0;
int x;
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "efae6c01779746258427f7315da3102e"; //Put your blink token
char ssid[] = "MikroTik Tesla"; //Put your SSID of your connection
char pass[] = "12345678"; //Put your Password of your connection
char server[] = "10.5.51.5";
SimpleTimer timer;
void setup()
{
Blynk.begin(auth, ssid, pass, server, 8080);
Serial.begin(9600);
pinMode(pirPin, INPUT);
digitalWrite(relayPin, 1); // high before pinMode stops relay chattering during bootup
pinMode(relayPin, OUTPUT);
pinMode(yellowledPin, OUTPUT);
pinMode(greenledPin, OUTPUT);
Serial.print(F("calibrating sensor "));
for (int i = 0; i < calibrationTime; i++)
{
Serial.print(F("."));
delay(1000);
}
Serial.println(F(" done"));
Serial.println(F("SENSOR ACTIVE"));
Serial.println(F("-------------"));
timer.setInterval(1000L, sense);
}
BLYNK_CONNECTED() {
Blynk.syncVirtual(V20);
}
BLYNK_WRITE(V20) {
x = param.asInt();
}
void sense() {
if (digitalRead(pirPin) && !alarmState)
{ // PIR active and no alarm
digitalWrite(relayPin, 0); // relay on
digitalWrite(greenledPin, HIGH); // LED on
Serial.println("motion detected");
Serial.println("Relay ON");
countDown = x * 3600L * 1000; // seconds
alarmState = HIGH; // remember it
}
if (countDown == 0 && alarmState)
{ // end of countdown and alarm
digitalWrite(relayPin, 1); // relay off
digitalWrite(greenledPin, LOW);
digitalWrite(yellowledPin, LOW);
Serial.println(F("Lights off"));
Serial.println(F("Relay OFF"));
Serial.println(F("---------"));
alarmState = LOW; // remember it
}
if (countDown > 0)
{
if (digitalRead(pirPin) == HIGH)
{ countDown = x * 3600L * 1000; // seconds
digitalWrite(yellowledPin, LOW);
digitalWrite(greenledPin, HIGH); // LED on
Serial.println(F("motion detected"));
}
if (digitalRead(pirPin) == LOW)
{ digitalWrite(greenledPin, LOW); // LED off
Serial.println(F("motion ended"));
}
// if countdown is still running
Serial.println(countDown);
if (countDown < 5)
{ // blink last 4sec
for (int i = 0; i < 5; i ++)
{
digitalWrite(yellowledPin, !digitalRead(yellowledPin)); // flip pinstate
delay(200);
}
}
else delay(1000); // no blink
countDown --; // -1
}
}
void loop()
{
Blynk.run();
timer.run();
// You can inject your own code or combine it with other sketches.
// Check other examples on how to communicate with Blynk. Remember
// to avoid delay() function!
