Hey everyone
I need help on a certain part of my design. Basically what I am doing is trying to monitor the battery voltage of a lithium ion battery. Now when it falls below a certain level or to a certain point say for example 2.9V, I want a device that will detect that the voltage is at a low level and immediately switch on a dc motor. I thought maybe using a voltage comparator to compare the voltage of the battery to a reference voltage set up by the potentiometers but I dont know how to design a schematic that will show what I want. Can someone help?
Thanks
Luis
