does anyone know how to read a voltage of around 15v with ads1115

bandmwhitt2013:
that would be fine i just don't know how to code that with the ads1115 i have no problem doing this with arduino adc but this is truly a different creature

If your code can correctly measure voltages from 0 to Vdd (5v), then just add the resistor divider network between the ADC and the voltage.

Here is a schematic with some explanation:
