The LM10 is an accurate 200mV reference with an opamp to amplify it and another opamp that is used as a comparator, in an 8-pins DIL case.
It can be used as an over-voltage or under-voltage sensor.
hi,
If your robot is controlled by a 16F877, this PIC has internal 10 bit analog to digital convertors. It would be very easy to monitor the battery voltage, use a resitive potential divider to keep the maximum voltage into the ADC <=+5V.
hi,
Have looked at the link, its using a PIC, so why dont you use an ADC input on your 16F877 to do the same job.
Unless you want a battery monitor/indicator external to the robot, if so, then a DVM would do the same job.
i have thought of the sugesstion of using the internal A/D converter to read the volts , and i think i can do that to read volts up to 5 Volts , using the 7805L.....but i need to measure more volts than 5 volts , 5 is so low......i think i need to measure up to 12 Volts.
how to do that ............ i'm sorry but i'm still beginner
