This is a Step by Step Video Tutorial which is easy to be followed. In this tutorial we will learn how the Arduino Analog Inputs pins work and make few examples using a potentiometer and a photocell.
These pins will act as non pwm digital pins. Welcome to the third Arduino Tutorial from our Arduino Tutorial Series.
#Arduino analog serial
* Created by This example code is in the public domain Tutorial page: This example reads the pressed button from an array of buttons connected to single analog pin and prints it to Serial Monitor. Creating a digital to analog converter (DAC) 8-bit using resistor ladder (R-2R Ladder) and implemented it in Arduino Uno to create signals. 3V ( in case of esp32 ) & from 0V to 5V ( in case of arduino uno) and these PWM signals (analog output) are used to dim (variable output, lighting the LED. Declare these pin numbers as integer (int) in arduino sketch, now make any analog pin as digital output pin.
