#40072 Hello,
I am a developer and I am new to ESP-8266.
I'm not an electronic expert.

I would like to make a circuit with Esp-12 for power on and off Arduino and for hardware reset Arduino.
I used two relays, one to cut power to Arduino and one to reset Arduino.

I tried with two different power sources, like the attached "schema 1" and it works fine.

When I tried to use the same power source, like the attached "schema 2", the relay for powering on and off Arduino works well, but when I use the relay to reset Arduino (I connected the Arduino reset pin to the ground with a 1000 ohm resistor) the ESP12 crashes.


Can you help me?
Thank you very much.
