    <h3>Group assignment</h3>
    <p>We were asked to observe the operation of a microcontroller circuit board.</p>
    <p>For that, we used our Quentorres + our "blink" Arduino code + an Arduino "fade" code and we checked the measurements with our RIGOL DS1054 oscilloscope.</p>

    <h5>The Arduino Blink Code</h5>
    <pre>
    <code>
    const int ledPin = 26;
    // the setup function runs once when you press reset or power the board
    void setup() {
    // initialize digital pin LED_BUILTIN as an output.
    pinMode(ledPin, OUTPUT);
    }
    // the loop function runs over and over again forever
    void loop() {
    digitalWrite(ledPin, HIGH); // turn the LED on (HIGH is the voltage level)
    delay(1000); // wait for a second
    digitalWrite(ledPin, LOW); // turn the LED off by making the voltage LOW
    delay(1000); // wait for a second
    }
    </code>
    </pre>
    <h5>The Arduino Fade Code</h5>
    <pre>
    <code>
    int led = 26; // the PWM pin the LED is attached to
    int brightness = 0; // how bright the LED is
    int fadeAmount = 5; // how many points to fade the LED by
    // the setup routine runs once when you press reset:
    void setup() {
    // declare pin to be an output:
    pinMode(led, OUTPUT);
    }
    // the loop routine runs over and over again forever:
    void loop() {
    // set the brightness
    analogWrite(led, brightness);
    // change the brightness for next time through the loop:
    brightness = brightness + fadeAmount;
    // reverse the direction of the fading at the ends of the fade:
    if (brightness <= 0 || brightness >= 255) {
    fadeAmount = -fadeAmount;
    }
    // wait for 100 milliseconds to see the dimming effect
    delay(100);
