I would like for you to write an arduino sketch for an LCD bar graph.
The device will read a voltage divider and display the results on a 2 x 16 LCD module.
The bottom line will be a bar graph.
The top line will show battery voltage and battery capacity from 0 - 100%
I was thinking that we could use a look up table to compare the voltage from a Lead acid discharge curve.
It would also like to have a jumper to select between 12 volt and 24 volt input and a 10 turn trimpot to manually calibrate the voltage.
Let me know if you would like to help me out
