Analog Read Serial

Intro

This example shows you how to read analog input from your NEXTuino device over serial communication. Connect a potentiometer to one analog input and establish serial communication between your NEXTuino board and your computer running the Arduino Software (IDE).

IMPORTANT: Please select the proper target board in Tools > Board > NEXTuino RISE/MAXI/MEGA before uploading to your NEXTuino.

Hardware Required

• NEXTuino RISE/MAXI/MEGA
• 10k ohm potentiometer

Code

#include <NEXTuino.h>

// the setup routine runs once when you press reset:
void setup() {
    // initialize the necessary pin as an input pin
    pinMode(NEXTuino_A0, INPUT);

    // initialize serial communication at 9600 bits per second:
    Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
    // read the input on analog pin 0:
    int sensorValue = analogRead(NEXTuino_A0);
    // print out the value you read:
    Serial.println(sensorValue);
    delay(1); // delay in between reads for stability
}

Note: The pin header is working on 5V TTL levels. Voltage levels over 5.5V can damage the NEXTuino permanently.
