I could not find any information in the data sheets about what the input impedance (s) of the analog input pins (A0-A5) were. I want to know if they would work for a certain experiment I'm running that requires that the voltmeter has an input impedance in the order of .AnalogWriteMega - Fade 12 LEDs on and off, one by one, using an Arduino Mega board. Calibration - Define a maximum and minimum for expected analog sensor values. Fading - Use an analog output (PWM pin) to fade an LED. Smoothing - Smooth multiple readings of an analog input. Last revision 2015/07/28 by SM

int sensorValue = analogRead (A0); To change the values from 0-1023 to a range that corresponds to the voltage the pin is reading, you'll need to create another variable, a float, and do a little math. To scale the numbers between 0.0 and 5.0, divide 5.0 by 1023.0 and multiply that by sensorValue : float voltage= sensorValue * (5.0 / 1023.0);

arduino analog eingang programmieren I have an Arduino Mega 2560, suddenly its analog inputs (A0 to A15) started reading the same value all the time without anything connected. The values of ADC output in ANY analog input are around 350~400 (decimal) The point is: It's reading always the same value and sum this value to any signal inputed. Example code used:

Also I think that the highest analogue reference voltage for the board is 5V. I have been looking into other ADCs recently, which have a higher resolution than the Arduino’s ADC. However, the analogue input has a really small range compared to Arduino Mega.
