Hi, I am measuring voltage on the voltage divider
Divider is powered from the same power supply as ADS1115. AIN0 connected to VDD, AIN1 to the voltage divider.
Theory: easy calculation gives me: VDD = 5V , R1=1k, R2=10k, V = 0.455
VDD 5V; measured 0.447V; expected 0.455V So far so good.
VDD 4.7064; Measured 0.3980V; expected: 0.4228V
Where is the problem?
