As mentioned in our previous post, we decided to read the temperature of
not just one finger, but three, as we thought this would provide a more
accurate reading. After gathering extra thermistors and wiring them, we rewrote
our code to average the temperature from the thermistors into one. Our
breadboard looked like a mess afterwards, but nonetheless, it was working.
Could it have been done with fewer wires? Probably.
Confident that our
code was ~*perfect*~ we moved towards something more permanent. We began
soldering our neopixels together once they arrived, and fastened our sensors
into place on the back of the acrylic hand. Once we got done hardwiring, we
realized that the code was going to need to change to accommodate all of the
new LEDs.
After
a much needed change of scenery, we went home to work on our project. After
countless trials and errors, we finally got the hand to work, and we weren't
the only ones who wanted to check our mood…
