Arduino IoT Cloud lesson 2: Potmeter

Step 1: Requirements

1X Arduino Nano 33 IoT

1X breadboard

3X jumper wires

1X 10K Potentiometer

Arduino Build

Step 2: Setup Arduino Create

For this project we are creating a new “Thing”. You can also use the “Thing” from the previous lesson, but to keep everything clear, let's start over.
If you create a new "Thing" and the same board you will be asked to unlink it. In this project, we've called it "Thing" Arduino-IoT-lesson-2-Potmeter.

When you have created your ”Thing” you can add another ”property”. In this project the property is a 10K Potmeter. We call this ”property” Potmeter_Angle. At the type we fill ”int" in. We enter 0 at the ”Min Value”. At the ”Max Value” we enter 270. 
In this project we select Read only at ”Permission”. We do this because we only have to read the value.
At ”Update” we select ”When the value changes ”and at” delta ”we enter 5. We enter 5 because it will only display a new value if the difference between the old and new value is greater than 5.

Step 2: Building and Wiring

Step 3: Programming

Now that you have finished wiring and building your Arduino IoT Potentiometer, you can start programming the Arduino Nano 33 IoT. We do this in the same way as in lesson 1. 

Below is the code you can use to make the potentiometer work.

#include "thingProperties.h"
#define POTENTIOMETER_PIN A0 // Here we define pin A0 as POTENTIOMETER_PIN

void setup () {
Serial.begin (9600);
delay (1500);

initProperties ();

ArduinoCloud.begin (ArduinoIoTPreferredConnection);

setDebugMessageLevel (2);
ArduinoCloud.printDebugInfo ();
}

void loop () {
ArduinoCloud.update ();
int AngleSensor = analogRead (POTENTIOMETER_PIN); // Here we ensure that the potentiometer is read
potmeter_Hoek = map (AngleSensor, 0, 1023, 0, 270); // Here we indicate what the values ​​of the potentiometer are
