Mutibit receiver

From the invention of the integrated circuit to surviving the Y2K problem, January has been an interesting month in history hardware. Here is a roundup of a few pieces of hardware history still saved in memory.

In this teardown, we take apart Vayyar's Walabot DIY In-Wall Imager to see what we can find.

We've all been there - you've spent hours and hours trying to get that sketch working, but somehow, you're not reacting well to time critical events in your system. Maybe it's a wireless peripheral indicating when a packet is ready. Maybe it's an external Flash device signaling when data is ready to be read out. Maybe it's as simple as a button push that you need to react quickly to! But, try as you might, it seems the best way to see these sort of events is to just `digitalRead()` that pin over and over in your main `loop()` function until something interesting happens. ...or is it?
