Il est possible de se procurer le kit fabriqué par Kuman contenant toute une série de capteurs analogiques qui permettent d’expériementer la programmation avec des résultats tangibles, le tout branché sur une carte Arduino. Les tutoriels étaient faits pour le Uno R3, mais la carte Uno R4 Wifi permet d’en faire autant, voire mieux, avec une pluis grande capacité de mémoire, de vitesse de processeur, bref, plein d’avenir!
Le Laser
La programmation pour tous les accessoires du kit Kuman reste semblable: c’est celle retrouvée dans les exemples fournis dans l’IDE d’Arduino dans la catégorie: Analog… AnalogInOutSignal.
De plus, on obtient des résultats dans la fenêtre de sortie Moniteur!
/*
Analog input, analog output, serial output
Reads an analog input pin, maps the result to a range from 0 to 255 and uses
the result to set the pulse width modulation (PWM) of an output pin.
Also prints the results to the Serial Monitor.
The circuit:
- potentiometer connected to analog pin 0.
Center pin of the potentiometer goes to the analog pin.
side pins of the potentiometer go to +5V and ground - LED connected from digital pin 9 to ground through 220 ohm resistor created 29 Dec. 2008

// These constants won’t change. They’re used to give names to the pins used:
const int analogInPin = A0; // Analog input pin that the potentiometer is attached to
const int analogOutPin = 9; // Analog output pin that the LED is attached to
int sensorValue = 0; // value read from the pot
int outputValue = 0; // value output to the PWM (analog out)
void setup() {
// initialize serial communications at 9600 bps:
Serial.begin(9600);
}
void loop() {
// read the analog in value:
sensorValue = analogRead(analogInPin);
// map it to the range of the analog out:
outputValue = map(sensorValue, 0, 1023, 0, 255);
// change the analog out value:
analogWrite(analogOutPin, outputValue);
// print the results to the Serial Monitor:
Serial.print(« sensor = « );
Serial.print(sensorValue);
Serial.print(« \t output = « );
Serial.println(outputValue);
// wait 2 milliseconds before the next loop for the analog-to-digital
// converter to settle after the last reading:
delay(2);

Le détecteur de température
Il est important de toujours identifier le S sur la carte, qui correspond à la pin du Signal, celle du milieu, la 5V et à l’autre extrémité, le Ground GND. Souvent on retrouve un LED qui s’allume au branchement. Ce code allume la Led #13, et à la détection d’un aimant, c’est la Led rouge sur la carte qui s’allume!
