Llevo toda la tarde intentando completar mi primer montaje con ESP8266 deAZ Delivery, se trata de el típico LED encendido desde BLYNK IoT.
El Sketch de arduino compila sin problemas.

El Dashboard de Blynk está correcto con Datastream virtual den V0 y el pin físico del LED es el D0.

Cuando pongo todo a funcionar no rula nada ni desde el dash del navegador ni desde la App de blynk.

- Fri Aug 26, 2022 10:20 am #95154 The components are not connected to each other (though I might incorrectly see it due to the angle of the photograph):

• Orange wire is connected between j15 and a4
• Resistor is connected between b5 and h5
• LED anode is connected to i? (isn't clear)
• LED cathode is connected to i8 (I think)
• Black wire is connected between j8 and j28

Make sure the orange cable is in the same row as the resistor (put it into a5) and check that the anode of the LED is connected to the same row as the resistor.

Also, there's a bug in your code: D0 on a NodeMCU is GPIO16, so change the following line in your code:

• Line 40: pinMode(16, OUTPUT);
• Line 49: digitalWrite(16, pinValue);

Good luck!

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
