8266 analogRead(A0) always 1024
First be sure your voltage on the analog input is less then 1V and greater then zero, that is the range for the input. If nothing connected no guarantee what you will get. Just guessing, no circuit or …

If I use a biasing circuit for a signal going into an analog input pin, will it affect the A...
For a 16 MHz Arduino the ADC clock is set to 16 MHz/128 = 125 KHz. Each conversion in AVR takes 13 ADC clocks so 125 KHz /13 = 9615 Hz. …

Inaccurate and non-precise voltage reading from Arduino Analog pin
This should be a lot of fun but you might consider doing some research on analog circuits and A/D circuits. You have way too many digits to the right of the decimal, the accuracy is not there. The bes …
