I do not know Erik how to do this. I need to measure the voltage of a 12v battery. I know I will be using a voltage divider to decrease the 12 volts and have an idea about the ratio like andy said. Whatever the voltage is on that battery I will be displaying it on a LCD from time to time. If the ADC pin can only acept 3 volts max. How can I show on the LCD that 3 volts is 12 volts on the battery, 2.9 is 11.9...so forth. How do you do that. Do you understand? |
