After a prolonged break from my Arduino experimentations I have finally made the time and, more crucially, room in my studio to return to the breadboard. It has not been a triumphant return. I could only remember the most basic facts about breadboarding, using electronic components and calculating resistance. Thankfully, I also had a whole new bag of funky components to break open, and after a little bit of online research, knowledge I had painstakingly acquired over the summer came flooding back to me in bits and pieces. I even vaguely remembered my plan (for which I had ordered said components) and how to go about executing it. However, of course my plan has changed since then and now I am unsure of how to combine the infinite variations of LEDs I have ordered in a meaningful way.
When looking over my components, the first surprise came when I inspected the Avago colour light sensor I had been so excited about in the summer. They say a picture is worth 1000 words, but to be honest I was still completely taken aback by the tiny size of this part, despite the useful size comparison picture next to it. How am I meant to solder that onto anything??? Briefly regretting not getting the fully assembled evaluation board instead (mainly because parts for wearable jewellery need to be tiny) I am now having to reconsider its immediate use in this project as I doubt my skills will advance quickly enough to make this part work (including all the programming). I had the foresight to order a simple optical sensor at the same time, and might use this instead in a more crude light/dark variation, which I might actually get to finish in time (the piece will be exhibited in March and needs to be delivered by February). As things stand right now, I will be over the moon if I even get the LEDs to work as I want them to and get all the soldering done on the components to fit them into the ‘chassis’, let alone complex colour sensing programming.
A significantly useful idea I have come across in my research is to add a ‘sleep’ function to an Arduino programme in order to prolong battery life by turning off any funtionality not needed when the board is in sleep mode. As anyone working with wearables is aware of, battery life is one of the major problems, and so finding a way to make a single charge last longer is a great step in the right direction. I found a brilliant tutorial at Sparkfun on the subject, but unfortunately it exceeds my budding Arduino skills as of yet. However, I am sure I will return to it in the not so distant future – food for thought!
