Problem is, the story of how the bears work won\u2019t interest everyone. For those of you that are interested, here you go.<\/p>\n<h3>Prototype versus Production<\/h3>\n<p>I needed to prove that the concept of \u201chugging a bear to light up a different bear\u201d was viable before they\u2019d proceed with the large quantities of bears so I undertook the prototype first.<\/p>\n<p>The first debate we had involved what type of board to use. They were undecided between wifi or cellular. I opted to go with <a href=\"https:\/\/www.particle.io\/\">Particle<\/a> primarily due to their having a board of each type; <a href=\"https:\/\/www.particle.io\/products\/hardware\/photon-wifi-dev-kit\">Photon<\/a> and <a href=\"https:\/\/www.particle.io\/products\/hardware\/electron-cellular-dev-kit\">Electron<\/a>. Also they have a cloud-based infrastructure that all of their boards can connect to and can be updated from.<\/p>\n<p><a href=\"https:\/\/hughqelliott.com\/blog\/wp-content\/uploads\/2017\/11\/particle_photo_electron.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-886\" src=\"https:\/\/hughqelliott.com\/blog\/wp-content\/uploads\/2017\/11\/particle_photo_electron.jpg\" alt=\"\" width=\"500\" height=\"375\" srcset=\"https:\/\/hughqelliott.com\/blog\/wp-content\/uploads\/2017\/11\/particle_photo_electron.jpg 500w, https:\/\/hughqelliott.com\/blog\/wp-content\/uploads\/2017\/11\/particle_photo_electron-420x315.jpg 420w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n<p>After working on the prototype, the following are the pros and cons I discovered;<\/p>\n<h4><strong>WIFI<\/strong><\/h4>\n<ul>\n<li><strong>pro<\/strong> fast. response time between boards was less than a second each time.
