Process and reflection:
[Your text goes here; at least 150 words. Address what your process was, e.g. what did you make/do first; how did it go; what did you make/do next; etc.
Include a reflection at a minimum addressing what you learned, any surprises along the way, and how you feel about where you ended up.]
Technical details
[Electrical schematic. Add a brief caption for clarity; this could be as simple as "Electrical schematic" but you can also use the space to describe anything that would be useful for your reader, e.g. "The 12V power came from a LiPo battery, not drawn."]
