How to read an Analog Input - Arduino IDE


On this post it will be shown how to read an Analog Input using Arduino IDE


Ethernet or 20 I/Os PLC:      Ethernet PLC             20 I/Os PLC     

Industrial Shields boards:   Industrial Shields Boards


The function for reading from a digital input using Arduino IDE is AnalogRead().  This function is used to read an analog signal (from 0 to 255).

 On Industrial Shields equipment’s is followed with the corresponding pinout. This functions are normally used inside the loop() function.

*With next version of Industrial Shields boards won’t be necessary to configure the pins, just selecting the properly board, I/O’s will be automatically configured. 

Next is showed the syntax:


Pin: Could be any industrial shields equipment pin or any Arduino board pin that you wish to set. 


Code Example, reading from an analoglRead:

void setup() { 

void loop() {
