ESP8266-12 on board led extension.


i have an ESP8266 and would like to parallel the on board led to an external led.

How do i do it?

Thx in advance.

You do not. Leds are current devices and are not designed to share. In series would work in some applications but in this one you do not have enough voltage. You can parallel it but you also need to parallel the resistor used on the original LED as well. Hopefully your soldering skills are up to the task!

Thank you!

i expressed myself wrong... i want to have it using the having a led driven by one of the gpios, flashing according the onboard led. :wink:

I think the LED is attached to GPIO3(Rx) on the ESP12? You can attach a LED to this pin through a series resistor?
