Analog Input Pins - Arduino Docs
The ATmega controllers used for the Arduino contain an onboard 6 channel (8 channels on the Mini and Nano, 16 on the Mega) analog-to-digital (A/D) converter. The converter has 10 bit resolution, returning integers from 0 to 1023. While the main function of the analog pins for most Arduino users is to read … See more
The analog pins can be used identically to the digital pins, using the aliases A0 (for analog input 0), A1, etc. For example, the code would look like this to set … See more
The analog pins also have pull-up resistors, which work identically to pull-up resistors on the digital pins. They are enabled by issuing a command such as Be aware … See more
The analogRead command will not work correctly if a pin has been previously set to an output, so if this is the case, set it back to an input before using … See more
Arduino UNO: Using Analog Input as Digital In/Out
Feb 6, 2013 · Reads an analog input on pin 0, converts it to voltage, and prints the result to the serial monitor. Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V …
Using Arduino Analog Pins As Digital Output Input Pins …
To use Arduino analog pin as a digital output pin, you need first to call the pinMode() function to set the pin mode to be OUTPUT. Then you can easily set the digital pin state using the digitalWrite() function as you’d do for any digital …
