    <h4>Quentorres programming</h4>
    <p></p>
    <p>We've already programmed the led to blink by pushing the button on the Quentorres on week04.</p>

    <p>This week we went a little further !</p>
    <p>First we programmed the 3 leds to blink all at ones every second with Arduino.</p>
    <pre>
    <code>
    //read leds on pin 26, 0 and 1(correspondance seeed studio component)
    const int ledPin0 = 26;
    const int ledPin1 = 0;
    const int ledPin2 = 1;
    // the setup function runs once when you press reset or power the board
    void setup() {
    // initialize digital pins as an output.
    pinMode(ledPin0, OUTPUT);
    pinMode(ledPin1, OUTPUT);
    pinMode(ledPin2, OUTPUT);
    }
    // the loop function runs over and over again forever
    void loop() {
    digitalWrite(ledPin0, HIGH); // turn the LEDs on (HIGH is the voltage level)
    digitalWrite(ledPin1, HIGH);
    digitalWrite(ledPin2, HIGH);
    delay(1000); // wait for a second
    digitalWrite(ledPin0, LOW); // turn the LEDs off (LOW is the voltage level)
    digitalWrite(ledPin1, LOW);
    digitalWrite(ledPin2, LOW);
    delay(1000); // wait for a second
    }
    </code>
    </pre>
    <span class="image object">
    <img src="../images/3-leds-blinking.mp4" alt="..." />
    </span>
    <p>The next step was to use the button again and turn the 3 leds on all at ones by pushing it.</p>
    <pre>
    <code>
    // Defining the pins
    const int boutonPin = 27;
    const int ledPin0 = 26;
    const int ledPin1 = 0;
    const int ledPin2 = 1;
    void setup() {
    // Configure the button as INPUT
    pinMode(boutonPin, INPUT);
    // Configure the LEDs as OUTPUT
    pinMode(ledPin0, OUTPUT);
    pinMode(ledPin1, OUTPUT);
    pinMode(ledPin2, OUTPUT);
    // Starting with the LEDs turned off
    digitalWrite(ledPin0, LOW);
    digitalWrite(ledPin1, LOW);
    digitalWrite(ledPin2, LOW);
    }
    void loop() {
    // Reading the button's state
    int etatBouton = digitalRead(boutonPin);
    // If the button is pushed
    if (etatBouton == HIGH) {
    // Turn on the LEDs
    digitalWrite(ledPin0, HIGH);
    digitalWrite(ledPin1, HIGH);
    digitalWrite(ledPin2, HIGH);
    } else {
    // Turn off the LEDs
    digitalWrite(ledPin0, LOW);
    digitalWrite(ledPin1, LOW);
    digitalWrite(ledPin2, LOW);
    }
    }
    </code>
    </pre>
    <span class="image object">
    <img src="../images/3-leds-blinking-button.mp4" alt="..." />
    </span>
    <p>Last step, I used the Arduino Serial Monitor to turn on and off the LEDs separately.</p>
    <p>For this program, I asked <a href="https://gemini.google.com/app/" target="_blank">Gemini</a> (Google's ChatGPT) for some help (because I'm no good at programming!) and it gave me this code :</p>
    <pre>
    <code>
    // Defining LEDs pins
    #define LED_26 26
    #define LED_1 1
    #define LED_0 0
    void setup() {
    // Initialize LEDs pins as OUTPUT
    pinMode(LED_26, OUTPUT);
    pinMode(LED_1, OUTPUT);
    pinMode(LED_0, OUTPUT);
    // Starting Serial Monitor
    Serial.begin(9600);
    }
    void loop() {
    // Declaring the variable that will stock the received character
    char c;
    // Waiting to receive the character
    while (!Serial.available());
    // Reading the received character
    c = Serial.read();
    // The LED that corresponds to the received character lights up
    switch (c) {
    case '1':
    digitalWrite(LED_26, HIGH);
    digitalWrite(LED_1, LOW);
    digitalWrite(LED_0, LOW);
    break;
    case '2':
    digitalWrite(LED_26, LOW);
    digitalWrite(LED_1, HIGH);
    digitalWrite(LED_0, LOW);
    break;
    case '3':
    digitalWrite(LED_26, LOW);
    digitalWrite(LED_1, LOW);
    digitalWrite(LED_0, HIGH);
    break;
    case '0':
    digitalWrite(LED_26, LOW);
    digitalWrite(LED_1, LOW);
    digitalWrite(LED_0, LOW);
    break;
    }
    }
    </code>
    </pre>
    <p>It results on :
    <ul>
    <li>turning on LED 26 by writing "1" in the serial monitor,</li>
    <li>turning on LED 1 by writing "2" in the serial monitor,</li>
    <li>turning on LED 0 by writing "3" in the serial monitor,</li>
    <li>turning all LEDs off by writing "0" in the serial monitor.</li>
    </ul>
    </p>
    <p>Here is the prompt I used in Gemini to get the code :
    <blockquote>
    code arduino serial monitor seeed rp2040 led pin 26, led pin1 and led pin0. When "1" is written in the serial monitor, led pin 26 lights up. When "2" is written in the serial monitor, led pin 1 lights up. When "3" is written in the serial monitor, led pin 0 lights up. When "0" is written in the serial monitor, all 3 leds go out.
    </blockquote>

    <span class="image object">
    <img src="../images/gemini-prog-test.mp4" alt="..." />
    </span>
    <p>As little extra, I installed and tried out <a href="https://thonny.org/" target="_blank">Thonny</a> to code in MicroPython.</p>
    <p>For that, I followed all the steps of the <a href="https://wiki.seeedstudio.com/XIAO-RP2040-with-MicroPython/" target="_blank">Seeed Studio wiki page MicroPython language</a> to get the RGB LED to blink in "Beautiful colors".</p>
    <p>So, after installing the Thonny Editor and connecting the Seeed Studio, it is asked to download the <a href="../files/ws2812.py" target="_blank">ws2812.py</a> library, open it in the Editor and save it on the "Raspberry Pi Pico".</p>
    <p>Here is the ws2812.py library content :</p>
    <pre>
    <code>
    import array, time
    from machine import Pin
    import rp2
    # Configure the number of WS2812 LEDs.
    #brightness = 0.2
    @rp2.asm_pio(sideset_init=rp2.PIO.OUT_LOW, out_shiftdir=rp2.PIO.SHIFT_LEFT, autopull=True,pull_thresh=24)
    def ws2812():
    T1 = 2
    T2 = 5
    T3 = 3
    wrap_target()
    label("bitloop")
    out(x, 1) .side(0) [T3 - 1]
    jmp(not_x, "do_zero") .side(1) [T1 - 1]
    jmp("bitloop") .side(1) [T2 - 1]
    label("do_zero")
    nop() .side(0) [T2 - 1]
    wrap()
    class WS2812():
    def __init__(self, pin_num, led_count, brightness = 0.5):
    self.Pin = Pin
    self.led_count = led_count
    self.brightness = brightness
    self.sm = rp2.StateMachine(0, ws2812, freq=8_000_000, sideset_base=Pin(pin_num))
    self.sm.active(1)
    self.ar = array.array("I", [0 for _ in range(led_count)])
    def pixels_show(self):
    dimmer_ar = array.array("I", [0 for _ in range(self.led_count)])
    for i,c in enumerate(self.ar):
    r = int(((c >> 8) & 0xFF) * self.brightness)
    g = int(((c >> 16) & 0xFF) * self.brightness)
    b = int((c & 0xFF) * self.brightness)
    dimmer_ar[i] = (g<<16) + (r<<8) + b
    self.sm.put(dimmer_ar, 8)
    time.sleep_ms(10)
    def pixels_set(self, i, color):
    self.ar[i] = (color[1]<<16) + (color[0]<<8) + color[2]
    def pixels_fill(self, color):
    for i in range(len(self.ar)):
    self.pixels_set(i, color)
    def color_chase(self,color, wait):
    for i in range(self.led_count):
    self.pixels_set(i, color)
    time.sleep(wait)
    self.pixels_show()
    time.sleep(0.2)
    def wheel(self, pos):
    # Input a value 0 to 255 to get a color value.
    # The colours are a transition r - g - b - back to r.
    if pos < 0 or pos > 255:
    return (0, 0, 0)
    if pos < 85:
    return (255 - pos * 3, pos * 3, 0)
    if pos < 170:
    pos -= 85
    return (0, 255 - pos * 3, pos * 3)
    pos -= 170
    return (pos * 3, 0, 255 - pos * 3)
    def rainbow_cycle(self, wait):
    for j in range(255):
    for i in range(self.led_count):
    rc_index = (i * 256 // self.led_count) + j
    self.pixels_set(i, self.wheel(rc_index & 255))
    self.pixels_show()
    time.sleep(wait)
    </code>
    </pre>
    <p>Then I had to open a new file and paste this code in it :</p>
    <pre>
    <code>
    from ws2812 import WS2812
    import utime
    import machine
    power = machine.Pin(11,machine.Pin.OUT)
    power.value(1)
    BLACK = (0, 0, 0)
    RED = (255, 0, 0)
    YELLOW = (255, 150, 0)
    GREEN = (0, 255, 0)
    CYAN = (0, 255, 255)
    BLUE = (0, 0, 255)
    PURPLE = (180, 0, 255)
    WHITE = (255, 255, 255)
    COLORS = (BLACK, RED, YELLOW, GREEN, CYAN, BLUE, PURPLE, WHITE)
    led = WS2812(12,1)#WS2812(pin_num,led_count)
    while True:
    print("Beautiful color")
    for color in COLORS:
    led.pixels_fill(color)
    led.pixels_show()
    utime.sleep(0.2)
    </code>
    </pre>
    <p>Finally, this code has to be uploaded by clicking the "Run current script" button. The location where it will be saved is not important. Both locations are fine.</p>
    <p>If it works well, you will see the RGB LED light convert and flash the lights. And the output of the text "Beautiful Color" will as well be displayed in the Shell.</p>
