Im looking for an IC that will send serial data to my pc indicating when my battery is low. Im using an axon ii and a sealed lead acid battery. Any suggestions are appreciated.
I am just looking for someway to let me know when I have approximately ten minutes left of charge.
How would I use one of the analog to digital converters? This is my first experience with the Axon II so as you can tell I am a bit newbie. Would I just set up a voltage divider circuit and connect it to the ADC pins? Also, I am not sure how I would program/ configure it?
if voltage < measured_10min_left_voltage print "low voltage" to serial
Ok thank you Admin. One problem though, the battery I am using is 12 volts so if I used three resistors, instead of to would my voltage be divided by three? Would this work?
24V battery -> switching regulator -> 12V output -> to electronics
What electronics do you have?
