Hi. I’m trying to activate a led using the On/off state widget but when I try to turn it on it it turns off immediately, doing nothing.
Any tip?
Hello sr,
It should a problem with your source code. Can you share it with us?
best!
Hi, Maybe this can help you.

I use ESP8266 NodeMCU(ESP-12). Pins 5,4,14 (please refer to the ESP8266 pin reference, I used pins 5,4,14 for some reason because it uses several sensors on other pins) each pin connected to a simple two-stage switch circuit. Remember the BJT on first stage will invert the logic.

Sorry, I only understand Portuguese (you speak Spanish) a bit and help with Google Translate. Let’s make it clearer. Do you mean you want to turn on the internal LED on Pin 2 with the widget (like your first question) as an alarm sign that the fire is already on?
Maybe this helps,

}
void setup() {
SecondTick.attach(1,ISRwatchdog);
thing.add_wifi(SSID, SSID_PASSWORD);
thing["millis"] >> outputValue(millis());
pinMode(2, OUTPUT); //LED or Relay to switch Buzzer and light as an ALARM (Manual Switch as you want)
dht.begin();
thing["DHT"] >> [](pson& out){
float cal_temp = -5.8;
float cal_hum = 8.1;
out["Humedad"] = dht.readHumidity();
out["Temperatura"] = dht.readTemperature();
};
thing["Fuego"] >> outputValue(!digitalRead(D1));
thing["ALARM"] << digitalPin(2); //Set your Widget as switch manual ALARM
thing["RSSI"] >> outputValue (WiFi.RSSI()); //additional: if you want to know how strong wifi signal
thing["MAC Address"] >> outputValue (WiFi.macAddress()); //additional: if you have another MCU and separated by MAC Address
}
void loop() {
WTDcount=0;
thing.handle();
}
Actually you can make an LED alarm or an automatic buzzer active by using the tutorial for controlling a digital pin just use the method explained in this resources section.
Really what I want is to turn on the relay (pin D5) with the flame sensor (to warn that there is fire) and with the widget (to use the relay as a remote switch).
Hello all,
I’m not pretty sure about your input resource structure… but please try with this:
thing["boton"] << [](pson & in) {
if(in.is_empty()){
in=(bool)digitalRead(llama);
}else{
digitalWrite(rele, in? HIGH:LOW);
digitalWrite(2, in? LOW:HIGH);
};
in this case, when the Pson has no data, the status will be the referred by the sensor read.
then, in your loop you will have to make a little hierarchy to prevent the status to change in the next execution, something like this:
void loop(){
thing.handle();
if(!remoto){
//Serial.print(fuego);
//Serial.print("\n");
digitalWrite(rele, !fuego);
digitalWrite(2, fuego);
}
}
