I’m attempting to use Blynk with an ESP8266-12E and a relay to switch my mains powered garden lights on/off. I am confident with mains lighting circuits but new to microcontrollers and the electonics knowledge required to use them. I have successfully used Blynk to switch an LED on a breadboard. I successfully tested a 5v relay to switch a lamp on/off using an Arduino. I then unsuccessfully tried to implement the circuit as seen in this image: http://imgur.com/a/U7RUm
It didn't work and I have wrecked the ESP8266. I am wondering if this is a problem with the capacitor. The friend helping me gave me a 1000uF capacitor but I read somewhere that Neil Kolban suggests a 10uF capacitor should be used for this purpose.
Can anyone offer any advice?
