Upgrades for the ambitious using IoT

Now that we’ve implemented the best solutions for creating this wearable and iterated to a prototype that has more features, including giving the wearer better information on the system state, we can look at features we may want to bring to future devices.

Often when I make a project that I really like, there are ways to improve or future-proof it, and this can involve switching to a different circuit board. Some of my earliest projects started on an Arduino Uno board, which is a lot larger than the boards we’ve been using. This meant that the wearable projects I made had a more cumbersome implementation or used more space than I would want for a prototype. When creating a proof-of-concept prototype, a larger board such as the Arduino Uno is perfectly acceptable, and we’ve seen in Chapter 8, Learning How to Prototype and Make Electronic Wearable, that using this board alongside 3D printer pens and TPU is a fun, inexpensive...
