Digital and Analog I/O. The Arduino UNO has 14 digital I/O pins and 6 Analog inputs. The digital I/O pins are 5V logic level and you can also use the Analog pins as digital I/O too. Arduino UNO ...

The “analogRead()” reads the value from the specified analog pin. Arduino Uno contains a multichannel 10-bit ADC (analog to digital converter). This means that it will map input voltages between 0 and ...

When working with Arduino boards for the ... Another common I/O pin misuse among beginners is using pins A4 and A5 on the Uno as regular analog input pins while also having an I2C device ...
