Is it possible to build electrical circuit with alarms for indicating Battery Power consumed in electronic gadgets viz cameras, toys, watches, calculators etc ?.
For example :
Similar to alarm which we manually set in clocks, the electrical circuit designed will calculate the battery power consumed and when it is say 10% battery power remaining (low on battery, drained), alarms will buzz to the consumer as warning signals before 2-3 days in advance for the respective electronic gadgets. This process will be automated.
If this is possible, alarms can be send to the Automobile drivers regarding recharging the vehicles batteries well in advance.
