Aside from the small workshop in grade 9, I have never encountered Arduino before and this is my first time working with it. Luckily the set I was given came with a manual that taught me the parts, and gave me different projects to do. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I decided to work on this digital hourglass project. <\/p>\n\n\n\n

The first step was to connect power and ground to the breadboard<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Next was to add the resistors needed<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Next we connect the rest of the wires that would create a circut through the led lights and resistors.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Then the led lights.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

However, at this point I realized I was using the wrong resistors. I had to search online to match the right 220ohm resistors. This then resulted in a torturing process of removing all of the resistors and replacing them.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The last part was to add a tilt switch as an addiontal function of turning off the timer. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

After finishing the physical project, we move into the digital space of coding the arduino block. The manual provided a nice line by line direction of what the code’s purpose. Here’s the general flow. <\/p>\n\n\n\n

    \n
  1. Setup<\/strong>\n
      \n
    • Set inputs and outputs to run the circut
      <\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Loop Begins<\/strong>\n
        \n
      • Store currentTime = millis()<\/code>
        <\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • (Decision)<\/strong> \n
          \n
        • Measure using the built in timer to tell if the time interval is up<\/li>\n\n\n\n
        • Yes<\/strong> \u2192 Proceed to turn on the next LED<\/li>\n\n\n\n
        • No<\/strong> \u2192 Skip to Step 6
          <\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Turn on Current LED<\/strong>\n
            \n
          • Reset the time interval
            <\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • Read Switch State<\/strong>\n
              \n
            • Tell if the switch is getting tilted<\/code>
              <\/li>\n<\/ul>\n<\/li>\n\n\n\n
            • (Decision)<\/strong>\n
                \n
              • If tilting then urn off all LEDs\n
                  \n
                • Reset everything else<\/li>\n<\/ul>\n<\/li>\n\n\n\n
                • If not then Continue
                  <\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
                  \"\"<\/figure>\n\n\n\n
                  \"\"<\/figure>\n\n\n\n
                  \"\"<\/figure>\n\n\n\n

                  Here’s the code in action. <\/p>\n\n\n\n
