I want to keep some state during a deep sleep of an ESP8266. To do this I used the following SR latch circuit:
It works well. The only change I made is that I used 2N2222 transistors.
The only problem is that this circuit uses S1 and S2 switches to change the state. On the breadboard I recreated this with some buttons.
Now I want to replace the buttons with a signal from the ESP.
I just started dabbling in the world of electronics and sending out HIGH signals is no problem for me, but I can't for the life of me figure out how to send this 'ground' signal from the ESP. It feels like I'm overlooking something very easy.
