How can I simply monitor battery voltage (12V deep cycle battery) with a microcontroller that has 0-5V only ADC?
Well, actually I want to use the microcontroller to monitor the battery voltage and prevent a sump pump to run if the voltage is too low (I dont want to damage the battery with a too deep discharge .)
Kind of a low-voltage battery cut-off.......
