HI, When button is pressed on app I can’t set timer to turn on relay for 10 seconds and then to turn it off. I add it on automation but it can be only set in minutes… not seconds. how to sove this? using blynk 2.0 and IOS app. Thanks!
Also when I try to add time input widget there is no datastreams to choose
Here is my code and setup!
//#define BLYNK_PRINT Serial
#include <BlynkSimpleEsp8266.h>
// define the GPIO connected with Relays and switches
#define RelayPin1 16
#define RelayPin2 4
#define SwitchPin1 10
#define SwitchPin2 0
#define wifiLed 17 //D0
#define VPIN_BUTTON_1 V1
#define VPIN_BUTTON_2 V2
int toggleState_1 = 1; //Define integer to remember the toggle state for relay 1
int toggleState_2 = 1; //Define integer to remember the toggle state for relay 2
int wifiFlag = 0;
#define AUTH "************"
#define WIFI_SSID "WiFi"
#define WIFI_PASS "************"
BlynkTimer timer;
void relayOnOff(int relay){
switch(relay){
case 1:
if(toggleState_1 == 1){
digitalWrite(RelayPin1, LOW); // turn on relay 1
toggleState_1 = 0;
Serial.println("Device1 ON");
}
else{
digitalWrite(RelayPin1, HIGH); // turn off relay 1
toggleState_1 = 1;
Serial.println("Device1 OFF");
}
delay(100);
break;
case 2:
if(toggleState_2 == 1){
digitalWrite(RelayPin2, LOW); // turn on relay 2
toggleState_2 = 0;
Serial.println("Device2 ON");
}
else{
digitalWrite(RelayPin2, HIGH); // turn off relay 2
toggleState_2 = 1;
Serial.println("Device2 OFF");
}
delay(100);
default : break;
}
}
