    <h3>Group assignment</h3> <h3>Assignment</h3>
    <p></p> <p>To measure output devices, as asked this week, we used a USB power meter (this one is from <a href="https://www.amazon.com/Keweisi-Charger-Detector-Battery-Capacity/dp/B0184Y14SK" target="_blank">Keweisi</a>).</p>
    <h4></h4> <span class="image object">
    <img src="../images/measurements-tool.jpg" alt="..." />
    </span>
    <p>But before measuring the power of the output devices, we made a little test/game : separate the output devices from the input devices.</p>
    <p>I did pretty well : one mistake + some could've been in both categories.</p>

    <h4>Coding</h4> <h4>Output tests</h4>
    <p>To test the different output devices, we used codes that already exist on internet or in Arduino.</p>
    <h5>LED Ring</h5>
    <span class="image object">
    <img src="../images/measuring-led-ring.jpg" alt="..." />
    </span>
    <p>For the LED ring, we used a simple code that can be found directly in Arduino.</p>
    <p>First, we had to add the LED ring's "Adafruit NeoPixel" library.</p>
    <p>After opening Arduino, you have to click on the library menu on the left sidebar, then search after "Adafruit NeoPixel".</p>
    <h5>The Arduino Neopixel simple code</h5> <span class="image object">
    <img src="../images/arduino-neopixel-lib.jpg" alt="..." />
    </span>
    <p>Once installed, open the "File" menu, go to "Examples", scroll until you see "Adafruit NeoPixel" and choose "simple".</p>

    <h5>The Arduino ... Code</h5> <blockquote>
    <p>Think about changing the number of the pin that is linked to the ring.</p>
    </blockquote>
    <p>The result is the LED ring getting each LED to turn on one after another until the last one. Then it starts again from the beginning.</p>

    <h5>OLED Display</h5>
    <p>As third test, we used an <a href="https://randomnerdtutorials.com/guide-for-oled-display-with-arduino/" target="_blank">I2C OLED Display</a>.</p>
    <p>To be more precise, we used the SSD1306 model: a monocolor, 0.96-inch display with 128×64 pixels.</p>
    <p>To be able to use it with Arduino, we had to install 2 libraries :</p>
    <ul>
    <li>Adafruit SSD1306</li>
    <li>Adafruit GFX Library</li>
    </ul>
    <p>Once both libraries are installed, we copy/paste <strong>the <a href="https://www.makerguides.com/how-to-interface-the-ssd1306-i2c-oled-graphic-display-with-arduino/" target="_blank">Makerguides I2C OLED Display Code for Arduino</a></strong> found on internet.</p>
    <p>I wanted to paste the code used on the OLED display here but it is interfering with the website.</p>
    <p>So the code file can be downloaded <a href="../files/screen.ino" target="_blank">here</a></p>
    <p>This code shows different texts and images on the display, so that we can see what can be done with this display.</p>
    <blockquote>
    <p>Think about changing the number of the pin that is linked to the display.</p>
