Our prototype is a low-fidelity (LoFi) build that showcases the on-arm design, with all the wiring and accessories readily available for use and testing. The on-arm design (to be later attached using other means) is equipped with a
functioning Circuit Playground Express (CPE), an Ultrasonic Sensor (USS), and a
battery pack for mobile or on-the-go use. The concept of our prototype in
relation to the chosen game is that as you control the character(s) on screen,
you’ll be doing so by manipulating your arm. As you tilt the character, you will
in turn tilt your arm in the direction needed to win the level. The same goes
for the movement, as you hover your hand above the USS, it acts like an
accelerator by having you “push down” to go forward and raise your hand up high
to go backward or even stop.
Some
questions we have would be:
1.
What other materials could be used to strengthen the overall design better than cardboard and painter’s tape?
2. How better could the wiring have been, or similarly, what other ways could the wiring be more efficient?
Explanation of the Wire Coloring
Black > Black = Ground
White > White = Echo
White > White + Black = Voltage Divider (Echo > Echo + Ground)
Red > Purple = 5v
Yellow > Brown/Green = Trig
