(Yes\u2013 the bracelet can have a more even weight distribution and more easily meet size requirements if it uses two small batteries.)<\/li>\n<li>How will wire management work? Now that most of our design will be on a PCB, the major wire connection remaining is the battery cable.<\/li>\n<li>\u00a0How many LEDs do we want to use? Because an array of NeoPixel LEDs can be connected to one output pin on the microcontroller, we can include more than the 6 LEDs we originally planned to have; however, more LEDs will draw more current, which will then decrease the battery life. Similarly, we can afford to have more than 3 (digital) microphones now, but it remains to be seen if this is necessary for our design.<\/li>\n<\/ul>\n<p>In another follow-up to last week\u2019s assignment, I <b>created an optional Google Form survey for the music studio<\/b>. Results from the Google Form seem to indicate that potential users would want a device with a long battery life. From the form answers, the longest duration of a music session could be 4 or 6 hours. Involvement with the music studio means that our use case is now more specific; we are aiming our product toward people who are regularly creating music and want to make sure that their practice\/rehearsal environments are safe. With these two assignments completed, <b>my progress matches our schedule<\/b>.<\/p>\n<p>This week, I <b>submitted orders<\/b> for the Beetle microcontroller (<a href=\"https:\/\/www.dfrobot.com\/product-2778.html\">https:\/\/www.dfrobot.com\/product-2778.html<\/a>) and NeoPixel LEDs (<a href=\"https:\/\/www.adafruit.com\/product\/3094\">https:\/\/www.adafruit.com\/product\/3094<\/a>) that we intend to use in our bracelet. Since we need to have all design decisions finalized by Sunday at midnight, which includes knowing all components that we will buy, <b>I am assigning myself the task of submitting all orders for materials in the coming week<\/b>.
