Working on a $5 Raspberry Pi

I’ve held off from buying a Raspberry Pi Zero for a while, in favor of Teensy or Pro Micro controllers, because what can a $5 controller really do?

I’ve been pleasantly surprised with the Zero so far. $5 got me a computer that’s half the size of a credit card, with HDMI video out, two USB ports, a GPIO header, and WIFI. Frickin’ WIFI!

Performance-wise, well, it’s pretty slow. But it’s fast enough for prototyping and running LEDs, which is great for my current project.
