How to regulate voltage. I'm going to be using a battery and have disigned something to warn me when it gets low and need's a recharge. But with this device I need exact voltage. I need a max voltage of 12v and not anything over, but as the battery dies the voltage does need to lower.

To regulate voltage, what's the difference between building a circuit using an IC and using a potentiometer in series with the power supply.

Is there a timer circuit that can actually shut down power. All the ones that I've seen will disconnect main power, reset them selves and turn into an oscillator.

Any answers you have will be appreciated
