Arduino UNO: Using Analog Input as Digital In/Out

Arduino - AnalogInputPins

Analog Pins which you are referring are for taking analog Inputs to your Arduino Board , that is for taking Input from Sensors like Photoresistor ,LDR . They use the ADC ( Analog to Digital -Converter ) chip to convert the analog values received into the digital form.

Using arduino analog inputs. Ask Question 3. I am creating my first Arduino program on the UNO r3. I have played with the Arduino Uno before just with petty example programs, etc. I have used a meter to measure the voltage on the analog input pins. all good there. just cant get the a-d to coorelate with my multimeter readings. – GoJo2332

Can I use the analog pins on the Arduino for my project as

Input impedance of Arduino Uno analog pins? Ask Question 17. 5 Together with the fact that there is no analog input leakage specified, I would guess that the ADC IO lines that are shared with digital IO have much more leakage current (1 uA from the docs) then the IO lines that are analog-only (50 nA, assuming that the SAR comparator is
