My voltage is 10v, so I have used a divider of 27k and 82k to bring the voltage down to 2.5 v.
The adc is still hitting 2.5 v.
I have check the output voltage of the equipment, and it is still within the 10v. ( 4.5 on one channel and 6.6 on the second).
Do I have to lower the resistance, ie 8.2k and 2.7k or lower?
