![]() The module is very useful for in-process controls, factory automation, industrial applications, etc. If we tried to measure a five volt range with a two-bit resolution, and the measured voltage was four volts, our ADC would return a numerical value of 3 as four volts falls between 3.75 and 5V.This is an isolated analog input module that is useful for interfacing Analog signals of various types originated from analog sensors and field devices. A 2-bit resolution would allow four (two to the power of two) values zero, one, two, and three. Measure the resolution in the terms of the number of bits of resolution.įor example, a 1-bit resolution would only allow two (two to the power of one) values zero and one. ![]() The higher the resolution, the greater accuracy with which something can be represented. The resolution is the degree to which something can be represented numerically. The analogRead() returns the value from 0 to1023, this is because of the resolution of the ADC. Potentiometer is connected at analog pin 0: ![]() This code measures analog signal from A0 pin of Arduino every one second and prints value on serial monitor. Let’s connect a potentiometer or variable resistor to the analog pin A0 into the Arduino board and provide supply to power on the Arduino Board.Īt a very start, need to define the pin as an input: pinMode(A0, INPUT) Īnd then reading the analog voltages through the analog pin A0 into the x: The function is used to program and address analog pins on the Arduino board and will also return the analog input reading which is between 0 to 1023.
