PWM to analog

Arduino Analog

    The 5V Arduino Boards reads and processes analog signals in a voltage range from 0 to 5 volts. The microcontroller of the Arduino board has an internal Analog-to-digital converter (ADC) for processing the analog input signals. The Arduino Uno, for instance, has six analog channels, in which six analog voltages (i.e. sensors) can be processed in parallel. The ports available for this purpose are labeled A0 to A5 on the Arduino Uno
