Im trying to create a circuit so that I can monitor the voltage drop on my battery and send an message when the voltage drop reaches the drop out. But I'm having some problems with my voltage divisions.
I created this circuit to enable a flow so that it does not flow (drain the battery) while not necessary. But as I understand it analog input must not be above 1 volts.
The +3.3V represent the MCU (ESP-12, arduino with wifi) turning the circuit on, letting battery flow to the analog input (red circled ground). However, at analog input, the volt is 2,24V, which is more than the 1V it should be. Do I just divide it again? If I divide it again ill be at 1,12 so I need to divide it yet again. I don't think Im doing it right.
The maximum voltage of the analog pin on the ESP-12 is 1V. How can I get there?
