How can I use a 12 V input on a digital Arduino pin
Here we are taking analog input form a potentiometer. And this input is shown on LED as PWM and analog values on Serial monitor. Arduino gives analog output in range of 0 to 255. Technically the output is digital but in the form of PWM, but it seems to be analog. Arduino Boards have 6 PWM(Analog Pins) these are PIN No. 3,5,6,9,10,11.

/12/2015Read about 'Analog pin value keep fluctuating in Arduino' on element14. I tried reading analog input for a switch. But the analog value is moving gradually from 0 to 1023 and back to 0 ,eventhough the switch is not pressed. generk4 Jun 12, 2015 10:04 AM (in response to balearicdynamics)

A NodeMCU has 10 bit ADC which means it scales an analog signal in a range of 0-1023. In this example an analog input is taken and it displayed on an LED and the serial monitor. In order to show the input result on LED, Mapping of input value is need. Thus mapping is done by dividing input values by 4. This tutorial is for NodeMCU on Arduino IDE.

NodeMCU Analog Input on Arduino IDE - Robo India
The Arduino can input and output analog signals as well as digital signals. An analog signal is one that can take on any number of values, unlike a digital signal which has only two values: HIGH and LOW. Mohammed Aquib Ansari 2018-12-06. Hey nice explanation on using Arduino’s Analog and Digital pins.
