You can do an awful lot with a seven-segment display, a dial and some imagination. Happily for us all, the good folks at Adafruit have metaphorical and literal buckets of all those things, and have come up with a project which is completely customisable, a lot of fun, and should hopefully teach you a thing or two about connected data.
Build a fun re-usable dashboard to show metrics and other information with LED displays and automotive gauges.
Full instructions are, as always, available over at Adafruit – let us know what you use yours for! (I’m thinking news ticker, weather, inbox, time until next meeting…)
