Hi, now that I’m almost finished work on my previous project (a proper raspberry pi laptop), I’m looking to move on to another project.
'Wearable’s seems to be the word on everyone’s lips at the moment, and so that’s definitely an avenue I want to try my hand at. Lots of people seem to be making funky flashy jumpers at the moment but I want to try something different. i’m talking about real wearables. I want to do make a smartwatch.
I’m going to start off by just having it display the time, and then move on to bigger and better things. I’m going to need a screen - I’m planning on using either the Nokia 5110 LCD or the Adafruit OLED unit. It looks as as if the OLED is the most power-efficient, which is obviously important (although the backlight won’t be on all the time), but I also need to consider how many pins are needed to drive it, as I need to have a teensy microcontroller.
That brings me on to the next point - which microcontroller to use? The ones I’ve seen so far which look viable are the Adafruit trinket, the Adafruit gemma, and the smaller official Arduino boards. It needs to be small, but with enough oomph and pins to drive the LCD, a bluetooth module, maybe a couple of buttons, and hopefully a Neopixel - maybe even a ring round the edge.
What are your thoughts? What do you think would work?
I’m still learning :)
