14: Spark is now Particle (?)


They say 681 other trademarks created confusion. Maybe. Maybe someone offered to sue them. Still very interesting company.

13: LED Bar Graph

I bought 3 of these from All Electronics (as I recall). $.50 each.
I assumed these were a 1-piece item, but nope:
note the +/– markings
Each separated LED is dimly marked too:
Too bad they didn't build the ground-side resistors in. Otherwise, the 2 pins neatly fit in adjacent breadboard rows -- and make for tidy wiring.
